We want to divide 57019725 by 644.

Step 1:
5 divided by 644 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 644

Advancing to step 2:
57 divided by 644 is 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 644

On to step 3:
644 can be fit into 570 0 times, resulting in a remainder of 570.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 570 and we're left with 570.
Include the next digit (1) from the dividend after 570, then repeat: 5701 / 644

Advancing to step 4:
5701 divided by 644 is 8 with a remainder of 549.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 5152 from 5701 leaves us with 549.
Grab the next digit (9) from the dividend, add it to 549, then carry on: 5499 / 644

Advancing to step 5:
If we divide 5499 by 644, we get 8 and a remainder of 347.
Write down 8 as next digit of the result. 
Result so far: 88.0
The remainder is 347 after subtracting 5152 from 5499.
Include the next digit (7) from the dividend after 347, then repeat: 3477 / 644

Moving on to step 6:
644 goes into 3477 5 times with a remainder of 257.
Use 5 as the next digit of our solution. 
Result so far: 885.0
Subtracting 3220 from 3477 leaves us with 257.
Fetch the next digit (2) from the dividend, attach it to 257 and continue: 2572 / 644

Going ahead to step 7:
644 can be fit into 2572 3 times, resulting in a remainder of 640.
Put 3 as the next digit of the answer. 
Result so far: 8853.0
Subtract 1932 from 2572 to get 640.
Include the next digit (5) from the dividend after 640, then repeat: 6405 / 644

Moving on to step 8:
644 goes into 6405 9 times with a remainder of 609.
Write down 9 as next digit of the result. 
Result so far: 88539.0
If we take 5796 away from 6405, we end up with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

On to step 9:
The number 644 fits into 6090 9 times, leaving a remainder of 294.
Record the quotient 9 as the next digit in the result. 
Result so far: 88539.9
Deduct 5796 from 6090 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
The number 644 fits into 2940 4 times, leaving a remainder of 364.
Put 4 as the next digit of the answer. 
Result so far: 88539.94
Deduct 2576 from 2940 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 11:
When dividing 3640 by 644, we get 5 with a remainder of 420.
The next digit of our result is 5. 
Result so far: 88539.945
Deduct 3220 from 3640 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 12:
The number 644 fits into 4200 6 times, leaving a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 88539.9456
Deduct 3864 from 4200 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 13:
The number 644 fits into 3360 5 times, leaving a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 88539.94565
If we subtract 3220 from 3360, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
644 goes into 1400 2 times with a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 88539.945652
Subtracting 1288 from 1400 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 15:
If we divide 1120 by 644, we get 1 and a remainder of 476.
Record the quotient 1 as the next digit in the result. 
Result so far: 88539.9456521
Subtract 644 from 1120 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 16:
If we divide 4760 by 644, we get 7 and a remainder of 252.
Write down 7 as next digit of the result. 
Result so far: 88539.94565217
If we take 4508 away from 4760, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Our division results in 88539.94565217 with a remaining 2.52e-07.
