We divide 21073992 by 57
Let's see how many times 57 fits into 21073992.

Moving on to step 1:
When dividing 2 by 57, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 57

On to step 2:
When dividing 21 by 57, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 57

Step 3:
When dividing 210 by 57, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 171 from 210 leaves us with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 57

Let's proceed to step 4:
397 divided by 57 is 6 with a remainder of 55.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 342 from 397 and we're left with 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 57

Let's proceed to step 5:
The number 57 fits into 553 9 times, leaving a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 369.0
If we subtract 513 from 553, we get 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 57

Step 6:
If we divide 409 by 57, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 3697.0
The remainder is 10 after subtracting 399 from 409.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 57

Moving on to step 7:
57 goes into 109 1 times with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 36971.0
If we subtract 57 from 109, we get 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 57

Advancing to step 8:
If we divide 522 by 57, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 369719.0
The remainder is 9 after subtracting 513 from 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
57 goes into 90 1 times with a remainder of 33.
The next digit of our result is 1. 
Result so far: 369719.1
Subtract 57 from 90 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
57 can be fit into 330 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 369719.15
Deduct 285 from 330 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
If we divide 450 by 57, we get 7 and a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 369719.157
Subtracting 399 from 450 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 12:
When dividing 510 by 57, we get 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 369719.1578
Subtract 456 from 510 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
The number 57 fits into 540 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 369719.15789
Subtracting 513 from 540 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 14:
57 goes into 270 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 369719.157894
If we subtract 228 from 270, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 15:
If we divide 420 by 57, we get 7 and a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 369719.1578947
The remainder is 21 after subtracting 399 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 16:
57 goes into 210 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 369719.15789473
Subtract 171 from 210 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 369719.15789473 with a balance of 3.9e-08.
