We look at the division of 99712 by 77 
We want to divide 99712 by 77.

Advancing to step 1:
When dividing 9 by 77, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 77

Advancing to step 2:
The number 77 fits into 99 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 77 from 99 to get 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 77

Advancing to step 3:
The number 77 fits into 227 2 times, leaving a remainder of 73.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 154 from 227 and we're left with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 77

Going ahead to step 4:
77 goes into 731 9 times with a remainder of 38.
The next digit of our result is 9. 
Result so far: 129.0
Subtract 693 from 731 to get 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 77

Moving on to step 5:
77 can be fit into 382 4 times, resulting in a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 1294.0
Subtracting 308 from 382 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.

Step 6:
740 divided by 77 is 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 1294.9
Subtracting 693 from 740 leaves us 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.

Advancing to step 7:
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: 1294.96
If we take 462 away from 470, we end up 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.

Moving on to step 8:
77 goes into 80 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1294.961
If we take 77 away from 80, we end up 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.

Step 9:
The number 77 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1294.961
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.

Going ahead to step 10:
77 can be fit into 300 3 times, resulting in a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 1294.96103
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.

On to step 11:
The number 77 fits into 690 8 times, leaving a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 1294.961038
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.

Moving on to step 12:
When dividing 740 by 77, we get 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 1294.9610389
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.

Let's proceed to step 13:
When dividing 470 by 77, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1294.96103896
If we take 462 away from 470, we end up 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.

Our division results in 1294.96103896 with a remaining 8e-09.
