We're dividing 786389 by 57 
We want to figure out the number of times 786389 can be divided by 57.

Moving on to step 1:
When dividing 7 by 57, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 57

Step 2:
If we divide 78 by 57, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 57 from 78, we get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 57

On 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
Subtracting 171 from 216 leaves us with 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 57

Step 4:
When dividing 453 by 57, we get 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 137.0
If we take 399 away from 453, we end up with 54.
Append the next digit (8) from the dividend to 54 and continue with: 548 / 57

Moving on to step 5:
When dividing 548 by 57, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 1379.0
Subtracting 513 from 548 leaves us with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 57

Going ahead to step 6:
359 divided by 57 is 6 with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 13796.0
The remainder is 17 after subtracting 342 from 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
The number 57 fits into 170 2 times, leaving a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 13796.2
If we take 114 away from 170, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
57 goes into 560 9 times with a remainder of 47.
The next digit of our result is 9. 
Result so far: 13796.29
If we take 513 away from 560, we end up with 47.
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:
57 goes into 470 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 13796.298
The remainder is 14 after subtracting 456 from 470.
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:
140 divided by 57 is 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 13796.2982
Subtracting 114 from 140 leaves us 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.

On to step 11:
When dividing 260 by 57, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 13796.29824
If we take 228 away from 260, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
The number 57 fits into 320 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 13796.298245
If we take 285 away from 320, we end up 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.

Step 13:
350 divided by 57 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 13796.2982456
Deduct 342 from 350 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
80 divided by 57 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 13796.29824561
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 13796.29824561 with a balance of 2.3e-08.
