We look at the division of 657429 by 77 
We're looking to find how many times 77 goes into 657429.

Step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 77

Step 2:
When dividing 65 by 77, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 77

On to step 3:
The number 77 fits into 657 8 times, leaving a remainder of 41.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 616 from 657 leaves us with 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 77

Advancing to step 4:
414 divided by 77 is 5 with a remainder of 29.
The next digit of our result is 5. 
Result so far: 85.0
The remainder is 29 after subtracting 385 from 414.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 77

Step 5:
77 goes into 292 3 times with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 853.0
If we take 231 away from 292, we end up with 61.
Append the next digit (9) from the dividend to 61 and continue with: 619 / 77

Advancing to step 6:
619 divided by 77 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 8538.0
Subtracting 616 from 619 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
77 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8538.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 77, we get 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 8538.03
If we subtract 231 from 300, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
If we divide 690 by 77, we get 8 and a remainder of 74.
The next digit of our result is 8. 
Result so far: 8538.038
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
The number 77 fits into 740 9 times, leaving a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 8538.0389
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
If we divide 470 by 77, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 8538.03896
The remainder is 8 after subtracting 462 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
80 divided by 77 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 8538.038961
Subtracting 77 from 80 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
If we divide 30 by 77, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 8538.038961
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
77 goes into 300 3 times with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 8538.03896103
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 8538.03896103 and a remainder of 6.9e-08.
