We're dividing 86866308 by 712 
We want to figure out the number of times 86866308 can be divided by 712.

Step 1:
When dividing 8 by 712, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 712

On to step 2:
The number 712 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 712

Advancing to step 3:
When dividing 868 by 712, we get 1 with a remainder of 156.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 712 from 868, we get 156.
Take the next digit (6) from the dividend and append it to 156, then repeat: 1566 / 712

Step 4:
The number 712 fits into 1566 2 times, leaving a remainder of 142.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 142 after subtracting 1424 from 1566.
Bring next digit (6) of the dividend behind the 142 and repeat the process: 1426 / 712

Moving on to step 5:
The number 712 fits into 1426 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Deduct 1424 from 1426 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 712

Step 6:
712 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 1220.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 712

Going ahead to step 7:
The number 712 fits into 230 0 times, leaving a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 12200.0
Subtracting 0 from 230 leaves us with 230.
Take the next digit (8) from the dividend and append it to 230, then repeat: 2308 / 712

Step 8:
If we divide 2308 by 712, we get 3 and a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 122003.0
Deduct 2136 from 2308 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 9:
1720 divided by 712 is 2 with a remainder of 296.
The next digit of our result is 2. 
Result so far: 122003.2
If we take 1424 away from 1720, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 10:
When dividing 2960 by 712, we get 4 with a remainder of 112.
The next digit of our result is 4. 
Result so far: 122003.24
The remainder is 112 after subtracting 2848 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 11:
When dividing 1120 by 712, we get 1 with a remainder of 408.
Record the quotient 1 as the next digit in the result. 
Result so far: 122003.241
Subtract 712 from 1120 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 12:
When dividing 4080 by 712, we get 5 with a remainder of 520.
Use 5 as the next digit of our solution. 
Result so far: 122003.2415
The remainder is 520 after subtracting 3560 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 13:
712 can be fit into 5200 7 times, resulting in a remainder of 216.
Use 7 as the next digit of our solution. 
Result so far: 122003.24157
Deduct 4984 from 5200 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 14:
If we divide 2160 by 712, we get 3 and a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 122003.241573
If we subtract 2136 from 2160, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 15:
240 divided by 712 is 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 122003.241573
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
712 goes into 2400 3 times with a remainder of 264.
Record the quotient 3 as the next digit in the result. 
Result so far: 122003.24157303
The remainder is 264 after subtracting 2136 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final outcome is 122003.24157303, with a leftover of 2.64e-07.
