We look at the division of 4844660 by 644 
Our goal is to divide 4844660 by 644.

Step 1:
4 divided by 644 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 644

Let's proceed to step 2:
644 goes into 48 0 times with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (4) from the dividend, attach it to 48 and continue: 484 / 644

Let's proceed to step 3:
The number 644 fits into 484 0 times, leaving a remainder of 484.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 484, we end up with 484.
Bring next digit (4) of the dividend behind the 484 and repeat the process: 4844 / 644

On to step 4:
If we divide 4844 by 644, we get 7 and a remainder of 336.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 4508 from 4844 and we're left with 336.
Take the next digit (6) from the dividend and append it to 336, then repeat: 3366 / 644

Going ahead to step 5:
When dividing 3366 by 644, we get 5 with a remainder of 146.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 3220 away from 3366, we end up with 146.
Take the next digit (6) from the dividend and append it to 146, then repeat: 1466 / 644

Going ahead to step 6:
644 goes into 1466 2 times with a remainder of 178.
Put 2 as the next digit of the answer. 
Result so far: 752.0
Deduct 1288 from 1466 and we're left with 178.
Fetch the next digit (0) from the dividend, attach it to 178 and continue: 1780 / 644

Let's proceed to step 7:
The number 644 fits into 1780 2 times, leaving a remainder of 492.
Use 2 as the next digit of our solution. 
Result so far: 7522.0
If we take 1288 away from 1780, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 8:
4920 divided by 644 is 7 with a remainder of 412.
The number 7 becomes the next digit in our result. 
Result so far: 7522.7
The remainder is 412 after subtracting 4508 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 9:
The number 644 fits into 4120 6 times, leaving a remainder of 256.
The next digit of our result is 6. 
Result so far: 7522.76
Subtract 3864 from 4120 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 10:
644 can be fit into 2560 3 times, resulting in a remainder of 628.
The number 3 becomes the next digit in our result. 
Result so far: 7522.763
Deduct 1932 from 2560 and we're left with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 11:
The number 644 fits into 6280 9 times, leaving a remainder of 484.
Use 9 as the next digit of our solution. 
Result so far: 7522.7639
Deduct 5796 from 6280 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 12:
When dividing 4840 by 644, we get 7 with a remainder of 332.
Put 7 as the next digit of the answer. 
Result so far: 7522.76397
The remainder is 332 after subtracting 4508 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Let's proceed to step 13:
3320 divided by 644 is 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 7522.763975
If we subtract 3220 from 3320, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
If we divide 1000 by 644, we get 1 and a remainder of 356.
The number 1 becomes the next digit in our result. 
Result so far: 7522.7639751
Subtracting 644 from 1000 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 15:
644 goes into 3560 5 times with a remainder of 340.
Put 5 as the next digit of the answer. 
Result so far: 7522.76397515
The remainder is 340 after subtracting 3220 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The quotient of the division is 7522.76397515, and the remainder is 3.4e-07.
