We're dividing 851392 by 57 
We want to figure out the number of times 851392 can be divided by 57.

Advancing to step 1:
8 divided by 57 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 57

On to step 2:
When dividing 85 by 57, we get 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 57 from 85 leaves us with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 57

Advancing to step 3:
57 can be fit into 281 4 times, resulting in a remainder of 53.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 53 after subtracting 228 from 281.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 57

Going ahead to step 4:
57 goes into 533 9 times with a remainder of 20.
The next digit of our result is 9. 
Result so far: 149.0
Deduct 513 from 533 and we're left with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 57

Advancing to step 5:
209 divided by 57 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 1493.0
Subtracting 171 from 209 leaves us with 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 57

Advancing to step 6:
382 divided by 57 is 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 14936.0
The remainder is 40 after subtracting 342 from 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
If we divide 400 by 57, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 14936.7
If we take 399 away from 400, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
57 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 14936.7
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
57 goes into 100 1 times with a remainder of 43.
The next digit of our result is 1. 
Result so far: 14936.701
If we subtract 57 from 100, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 10:
57 can be fit into 430 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 14936.7017
If we subtract 399 from 430, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
310 divided by 57 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 14936.70175
Deduct 285 from 310 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
250 divided by 57 is 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 14936.701754
The remainder is 22 after subtracting 228 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
The number 57 fits into 220 3 times, leaving a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 14936.7017543
Subtract 171 from 220 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 14:
If we divide 490 by 57, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 14936.70175438
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 14936.70175438 with a balance of 3.4e-08.
