802121 divided by 57 
We want to figure out the number of times 802121 can be divided by 57.

Let's proceed to step 1:
57 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 57

Let's proceed to step 2:
The number 57 fits into 80 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 23 after subtracting 57 from 80.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 57

Step 3:
The number 57 fits into 232 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 228 from 232 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 57

Step 4:
41 divided by 57 is 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 140.0
If we take 0 away from 41, we end up with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 57

Moving on to step 5:
412 divided by 57 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 1407.0
Subtracting 399 from 412 leaves us with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 57

Advancing to step 6:
If we divide 131 by 57, we get 2 and a remainder of 17.
The next digit of our result is 2. 
Result so far: 14072.0
Subtract 114 from 131 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
When dividing 170 by 57, we get 2 with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 14072.2
The remainder is 56 after subtracting 114 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
57 can be fit into 560 9 times, resulting in a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 14072.29
The remainder is 47 after subtracting 513 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
If we divide 470 by 57, we get 8 and a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 14072.298
If we take 456 away from 470, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
57 goes into 140 2 times with a remainder of 26.
The next digit of our result is 2. 
Result so far: 14072.2982
If we take 114 away from 140, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
260 divided by 57 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 14072.29824
If we subtract 228 from 260, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
The number 57 fits into 320 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 14072.298245
Deduct 285 from 320 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
57 can be fit into 350 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 14072.2982456
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
57 goes into 80 1 times with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 14072.29824561
Deduct 57 from 80 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 14072.29824561 with a balance of 2.3e-08.
