786891 divided by 57 
We want to figure out the number of times 786891 can be divided by 57.

Step 1:
7 divided by 57 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 57

Moving on to step 2:
The number 57 fits into 78 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 57 from 78 to get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 57

Advancing to step 3:
When dividing 216 by 57, we get 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 171 from 216 and we're left with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 57

Step 4:
57 can be fit into 458 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 138.0
Deduct 456 from 458 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 57

Advancing to step 5:
29 divided by 57 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 1380.0
Deduct 0 from 29 and we're left with 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 57

Going ahead to step 6:
57 can be fit into 291 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 13805.0
Subtract 285 from 291 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 57 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 13805.1
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
The number 57 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 13805.1
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
57 can be fit into 300 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 13805.105
If we subtract 285 from 300, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
150 divided by 57 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 13805.1052
Deduct 114 from 150 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
57 goes into 360 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 13805.10526
If we subtract 342 from 360, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
If we divide 180 by 57, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 13805.105263
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
When dividing 90 by 57, we get 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 13805.1052631
Deduct 57 from 90 and we're left with 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 14:
If we divide 330 by 57, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 13805.10526315
If we subtract 285 from 330, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 13805.10526315 with a balance of 4.5e-08.
