We're dividing 88814746 by 644 
We want to figure out the number of times 88814746 can be divided by 644.

Step 1:
8 divided by 644 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 644

Step 2:
The number 644 fits into 88 0 times, leaving a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Grab the next digit (8) from the dividend, add it to 88, then carry on: 888 / 644

Moving on to step 3:
When dividing 888 by 644, we get 1 with a remainder of 244.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 644 from 888 to get 244.
Bring next digit (1) of the dividend behind the 244 and repeat the process: 2441 / 644

Step 4:
The number 644 fits into 2441 3 times, leaving a remainder of 509.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1932 away from 2441, we end up with 509.
Include the next digit (4) from the dividend after 509, then repeat: 5094 / 644

Going ahead to step 5:
5094 divided by 644 is 7 with a remainder of 586.
Write down 7 as next digit of the result. 
Result so far: 137.0
If we take 4508 away from 5094, we end up with 586.
Append the next digit (7) from the dividend to 586 and continue with: 5867 / 644

On to step 6:
If we divide 5867 by 644, we get 9 and a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 1379.0
The remainder is 71 after subtracting 5796 from 5867.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 644

Going ahead to step 7:
644 goes into 714 1 times with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 13791.0
Deduct 644 from 714 and we're left with 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 644

Advancing to step 8:
The number 644 fits into 706 1 times, leaving a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 137911.0
The remainder is 62 after subtracting 644 from 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
644 can be fit into 620 0 times, resulting in a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 137911.0
Subtracting 0 from 620 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 10:
6200 divided by 644 is 9 with a remainder of 404.
Write down 9 as next digit of the result. 
Result so far: 137911.09
If we take 5796 away from 6200, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 11:
644 goes into 4040 6 times with a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 137911.096
Subtracting 3864 from 4040 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 12:
The number 644 fits into 1760 2 times, leaving a remainder of 472.
Write down 2 as next digit of the result. 
Result so far: 137911.0962
If we subtract 1288 from 1760, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 13:
When dividing 4720 by 644, we get 7 with a remainder of 212.
Put 7 as the next digit of the answer. 
Result so far: 137911.09627
If we take 4508 away from 4720, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 14:
When dividing 2120 by 644, we get 3 with a remainder of 188.
Put 3 as the next digit of the answer. 
Result so far: 137911.096273
Deduct 1932 from 2120 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 15:
If we divide 1880 by 644, we get 2 and a remainder of 592.
Record the quotient 2 as the next digit in the result. 
Result so far: 137911.0962732
Subtracting 1288 from 1880 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 16:
The number 644 fits into 5920 9 times, leaving a remainder of 124.
Put 9 as the next digit of the answer. 
Result so far: 137911.09627329
If we subtract 5796 from 5920, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The quotient of the division is 137911.09627329, and the remainder is 1.24e-07.
