86710451 ÷ 76 
We want to figure out the number of times 86710451 can be divided by 76.

Let's proceed to step 1:
If we divide 8 by 76, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 76

Going ahead to step 2:
If we divide 86 by 76, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 76 away from 86, we end up with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 76

Moving on to step 3:
107 divided by 76 is 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 76 from 107 to get 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 76

Going ahead to step 4:
The number 76 fits into 311 4 times, leaving a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Deduct 304 from 311 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 76

Moving on to step 5:
76 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 1140.0
The remainder is 70 after subtracting 0 from 70.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 76

Going ahead to step 6:
If we divide 704 by 76, we get 9 and a remainder of 20.
The next digit of our result is 9. 
Result so far: 11409.0
Deduct 684 from 704 and we're left with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 76

Let's proceed to step 7:
The number 76 fits into 205 2 times, leaving a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 114092.0
The remainder is 53 after subtracting 152 from 205.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 76

Going ahead to step 8:
531 divided by 76 is 6 with a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 1140926.0
If we subtract 456 from 531, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
76 goes into 750 9 times with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 1140926.9
Deduct 684 from 750 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
76 goes into 660 8 times with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 1140926.98
Subtract 608 from 660 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
When dividing 520 by 76, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 1140926.986
Deduct 456 from 520 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
The number 76 fits into 640 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 1140926.9868
If we take 608 away from 640, 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.

On to step 13:
76 can be fit into 320 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1140926.98684
Subtracting 304 from 320 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
The number 76 fits into 160 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1140926.986842
The remainder is 8 after subtracting 152 from 160.
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 15:
76 goes into 80 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1140926.9868421
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 16:
If we divide 40 by 76, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1140926.9868421
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 1140926.9868421, and the remainder is 4e-08.
