We're dividing 86640623 by 711 
We want to figure out the number of times 86640623 can be divided by 711.

Moving on to step 1:
8 divided by 711 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 711

Step 2:
711 goes into 86 0 times with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 711

Going ahead to step 3:
When dividing 866 by 711, we get 1 with a remainder of 155.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 711 from 866, we get 155.
Bring next digit (4) of the dividend behind the 155 and repeat the process: 1554 / 711

Moving on to step 4:
If we divide 1554 by 711, we get 2 and a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1422 from 1554 leaves us with 132.
Append the next digit (0) from the dividend to 132 and continue with: 1320 / 711

On to step 5:
If we divide 1320 by 711, we get 1 and a remainder of 609.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Deduct 711 from 1320 and we're left with 609.
Include the next digit (6) from the dividend after 609, then repeat: 6096 / 711

Step 6:
711 goes into 6096 8 times with a remainder of 408.
The number 8 becomes the next digit in our result. 
Result so far: 1218.0
Subtracting 5688 from 6096 leaves us with 408.
Include the next digit (2) from the dividend after 408, then repeat: 4082 / 711

Advancing to step 7:
711 can be fit into 4082 5 times, resulting in a remainder of 527.
Put 5 as the next digit of the answer. 
Result so far: 12185.0
If we take 3555 away from 4082, we end up with 527.
Append the next digit (3) from the dividend to 527 and continue with: 5273 / 711

Advancing to step 8:
The number 711 fits into 5273 7 times, leaving a remainder of 296.
The next digit of our result is 7. 
Result so far: 121857.0
The remainder is 296 after subtracting 4977 from 5273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 9:
When dividing 2960 by 711, we get 4 with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 121857.4
If we take 2844 away from 2960, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 10:
1160 divided by 711 is 1 with a remainder of 449.
Put 1 as the next digit of the answer. 
Result so far: 121857.41
If we take 711 away from 1160, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Advancing to step 11:
If we divide 4490 by 711, we get 6 and a remainder of 224.
Write down 6 as next digit of the result. 
Result so far: 121857.416
Subtracting 4266 from 4490 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
2240 divided by 711 is 3 with a remainder of 107.
The next digit of our result is 3. 
Result so far: 121857.4163
The remainder is 107 after subtracting 2133 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 13:
If we divide 1070 by 711, we get 1 and a remainder of 359.
The next digit of our result is 1. 
Result so far: 121857.41631
If we subtract 711 from 1070, we get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Going ahead to step 14:
3590 divided by 711 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 121857.416315
Subtract 3555 from 3590 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 15:
The number 711 fits into 350 0 times, leaving a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 121857.416315
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 16:
711 goes into 3500 4 times with a remainder of 656.
Use 4 as the next digit of our solution. 
Result so far: 121857.41631504
The remainder is 656 after subtracting 2844 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

The quotient of the division is 121857.41631504, and the remainder is 6.56e-07.
