We look at the division of 721897 by 57 
Let's see how many times 57 fits into 721897.

Going ahead to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 57

Step 2:
72 divided by 57 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 57 from 72.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 57

Moving on to step 3:
When dividing 151 by 57, we get 2 with a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 37 after subtracting 114 from 151.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 57

Advancing to step 4:
If we divide 378 by 57, we get 6 and a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Subtracting 342 from 378 leaves us with 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 57

On to step 5:
When dividing 369 by 57, we get 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 1266.0
If we subtract 342 from 369, we get 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 57

Step 6:
57 goes into 277 4 times with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 12664.0
Deduct 228 from 277 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
57 can be fit into 490 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 12664.8
Subtracting 456 from 490 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
When dividing 340 by 57, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 12664.85
The remainder is 55 after subtracting 285 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
57 can be fit into 550 9 times, resulting in a remainder of 37.
The next digit of our result is 9. 
Result so far: 12664.859
If we subtract 513 from 550, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
370 divided by 57 is 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 12664.8596
If we take 342 away from 370, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
57 goes into 280 4 times with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 12664.85964
If we take 228 away from 280, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
The number 57 fits into 520 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 12664.859649
If we subtract 513 from 520, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
If we divide 70 by 57, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 12664.8596491
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
If we divide 130 by 57, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12664.85964912
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 12664.85964912 with a remaining 1.6e-08.
