We look at the division of 857658 by 77 
We're looking to find how many times 77 goes into 857658.

Let's proceed to step 1:
The number 77 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 77

Going ahead to step 2:
77 can be fit into 85 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 77 from 85 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 77

Step 3:
77 goes into 87 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 77 away from 87, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 77

Advancing to step 4:
If we divide 106 by 77, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
If we subtract 77 from 106, we get 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 77

Moving on to step 5:
77 goes into 295 3 times with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 1113.0
Deduct 231 from 295 and we're left with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 77

Advancing to step 6:
The number 77 fits into 648 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 11138.0
Subtracting 616 from 648 leaves us 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.

Advancing to step 7:
320 divided by 77 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 11138.4
The remainder is 12 after subtracting 308 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
If we divide 120 by 77, we get 1 and a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 11138.41
Deduct 77 from 120 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
77 can be fit into 430 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 11138.415
The remainder is 45 after subtracting 385 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
The number 77 fits into 450 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 11138.4155
The remainder is 65 after subtracting 385 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 11138.4155 with a balance of 0.00065.
