89038248 divided by 644 
Our goal is to divide 89038248 by 644.

On to step 1:
When dividing 8 by 644, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 644

Let's proceed to step 2:
644 can be fit into 89 0 times, resulting in a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (0) from the dividend, attach it to 89 and continue: 890 / 644

Let's proceed to step 3:
If we divide 890 by 644, we get 1 and a remainder of 246.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 644 from 890 and we're left with 246.
Take the next digit (3) from the dividend and append it to 246, then repeat: 2463 / 644

Advancing to step 4:
644 can be fit into 2463 3 times, resulting in a remainder of 531.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1932 away from 2463, we end up with 531.
Grab the next digit (8) from the dividend, add it to 531, then carry on: 5318 / 644

Moving on to step 5:
The number 644 fits into 5318 8 times, leaving a remainder of 166.
The next digit of our result is 8. 
Result so far: 138.0
Subtracting 5152 from 5318 leaves us with 166.
Take the next digit (2) from the dividend and append it to 166, then repeat: 1662 / 644

Going ahead to step 6:
644 goes into 1662 2 times with a remainder of 374.
Use 2 as the next digit of our solution. 
Result so far: 1382.0
If we take 1288 away from 1662, we end up with 374.
Take the next digit (4) from the dividend and append it to 374, then repeat: 3744 / 644

Going ahead to step 7:
If we divide 3744 by 644, we get 5 and a remainder of 524.
Put 5 as the next digit of the answer. 
Result so far: 13825.0
Subtracting 3220 from 3744 leaves us with 524.
Bring next digit (8) of the dividend behind the 524 and repeat the process: 5248 / 644

Let's proceed to step 8:
The number 644 fits into 5248 8 times, leaving a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 138258.0
If we take 5152 away from 5248, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
The number 644 fits into 960 1 times, leaving a remainder of 316.
Record the quotient 1 as the next digit in the result. 
Result so far: 138258.1
If we subtract 644 from 960, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 10:
The number 644 fits into 3160 4 times, leaving a remainder of 584.
Use 4 as the next digit of our solution. 
Result so far: 138258.14
Subtracting 2576 from 3160 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 11:
644 goes into 5840 9 times with a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 138258.149
Subtracting 5796 from 5840 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
If we divide 440 by 644, we get 0 and a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 138258.149
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 13:
4400 divided by 644 is 6 with a remainder of 536.
Use 6 as the next digit of our solution. 
Result so far: 138258.14906
The remainder is 536 after subtracting 3864 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 14:
The number 644 fits into 5360 8 times, leaving a remainder of 208.
The next digit of our result is 8. 
Result so far: 138258.149068
Subtracting 5152 from 5360 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 15:
644 can be fit into 2080 3 times, resulting in a remainder of 148.
Use 3 as the next digit of our solution. 
Result so far: 138258.1490683
Deduct 1932 from 2080 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 16:
The number 644 fits into 1480 2 times, leaving a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 138258.14906832
Subtract 1288 from 1480 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The quotient of the division is 138258.14906832, and the remainder is 1.92e-07.
