We look at the division of 21251111 by 57 
We're looking to find how many times 57 goes into 21251111.

On to step 1:
If we divide 2 by 57, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 57

On to step 2:
21 divided by 57 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 57

Going ahead to step 3:
When dividing 212 by 57, we get 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 171 from 212 and we're left with 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 57

Moving on to step 4:
The number 57 fits into 415 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 399 from 415 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 57

On to step 5:
If we divide 161 by 57, we get 2 and a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 372.0
Subtracting 114 from 161 leaves us with 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 57

Going ahead to step 6:
57 can be fit into 471 8 times, resulting in a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 3728.0
The remainder is 15 after subtracting 456 from 471.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 57

Moving on to step 7:
57 goes into 151 2 times with a remainder of 37.
The next digit of our result is 2. 
Result so far: 37282.0
The remainder is 37 after subtracting 114 from 151.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 57

Advancing to step 8:
371 divided by 57 is 6 with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 372826.0
The remainder is 29 after subtracting 342 from 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
290 divided by 57 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 372826.5
Subtracting 285 from 290 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
If we divide 50 by 57, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 372826.5
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
57 can be fit into 500 8 times, resulting in a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 372826.508
If we subtract 456 from 500, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
440 divided by 57 is 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 372826.5087
Subtracting 399 from 440 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
When dividing 410 by 57, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 372826.50877
If we take 399 away from 410, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 372826.50877 with a balance of 1.1e-05.
