8012991 ÷ 770 
We're looking to find how many times 770 goes into 8012991.

On to step 1:
When dividing 8 by 770, we get 0 with 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 (0) from the dividend, attach it to 8 and continue: 80 / 770

Let's proceed to step 2:
770 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 770

Step 3:
801 divided by 770 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 31 after subtracting 770 from 801.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 770

Moving on to step 4:
770 can be fit into 312 0 times, resulting in a remainder of 312.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 312 leaves us with 312.
Bring next digit (9) of the dividend behind the 312 and repeat the process: 3129 / 770

Moving on to step 5:
770 goes into 3129 4 times with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 3080 from 3129 to get 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 770

Moving on to step 6:
If we divide 499 by 770, we get 0 and a remainder of 499.
Record the quotient 0 as the next digit in the result. 
Result so far: 1040.0
Deduct 0 from 499 and we're left with 499.
Grab the next digit (1) from the dividend, add it to 499, then carry on: 4991 / 770

Step 7:
770 goes into 4991 6 times with a remainder of 371.
The number 6 becomes the next digit in our result. 
Result so far: 10406.0
The remainder is 371 after subtracting 4620 from 4991.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 8:
770 can be fit into 3710 4 times, resulting in a remainder of 630.
The number 4 becomes the next digit in our result. 
Result so far: 10406.4
If we subtract 3080 from 3710, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 9:
6300 divided by 770 is 8 with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 10406.48
If we take 6160 away from 6300, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
770 goes into 1400 1 times with a remainder of 630.
The next digit of our result is 1. 
Result so far: 10406.481
The remainder is 630 after subtracting 770 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 11:
770 goes into 6300 8 times with a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 10406.4818
Subtract 6160 from 6300 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
1400 divided by 770 is 1 with a remainder of 630.
The number 1 becomes the next digit in our result. 
Result so far: 10406.48181
If we subtract 770 from 1400, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 13:
If we divide 6300 by 770, we get 8 and a remainder of 140.
Write down 8 as next digit of the result. 
Result so far: 10406.481818
The remainder is 140 after subtracting 6160 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 14:
770 goes into 1400 1 times with a remainder of 630.
Write down 1 as next digit of the result. 
Result so far: 10406.4818181
Subtracting 770 from 1400 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 15:
6300 divided by 770 is 8 with a remainder of 140.
Write down 8 as next digit of the result. 
Result so far: 10406.48181818
The remainder is 140 after subtracting 6160 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 10406.48181818 with a remaining 1.4e-07.
