Let's divide 86721598 by 412
We're looking to find how many times 412 goes into 86721598.

Step 1:
When dividing 8 by 412, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 412

Let's proceed to step 2:
412 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 412

Step 3:
412 goes into 867 2 times with a remainder of 43.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 824 from 867, we get 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 412

Step 4:
If we divide 432 by 412, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 412 from 432, we get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 412

On to step 5:
412 goes into 201 0 times with a remainder of 201.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
Subtract 0 from 201 to get 201.
Grab the next digit (5) from the dividend, add it to 201, then carry on: 2015 / 412

Advancing to step 6:
412 goes into 2015 4 times with a remainder of 367.
Write down 4 as next digit of the result. 
Result so far: 2104.0
Subtracting 1648 from 2015 leaves us with 367.
Fetch the next digit (9) from the dividend, attach it to 367 and continue: 3679 / 412

On to step 7:
412 can be fit into 3679 8 times, resulting in a remainder of 383.
The next digit of our result is 8. 
Result so far: 21048.0
The remainder is 383 after subtracting 3296 from 3679.
Fetch the next digit (8) from the dividend, attach it to 383 and continue: 3838 / 412

Moving on to step 8:
412 goes into 3838 9 times with a remainder of 130.
The number 9 becomes the next digit in our result. 
Result so far: 210489.0
If we take 3708 away from 3838, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 9:
If we divide 1300 by 412, we get 3 and a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 210489.3
If we take 1236 away from 1300, we end up 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 10:
640 divided by 412 is 1 with a remainder of 228.
Record the quotient 1 as the next digit in the result. 
Result so far: 210489.31
The remainder is 228 after subtracting 412 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
2280 divided by 412 is 5 with a remainder of 220.
Use 5 as the next digit of our solution. 
Result so far: 210489.315
Subtracting 2060 from 2280 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 12:
If we divide 2200 by 412, we get 5 and a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 210489.3155
Subtract 2060 from 2200 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.

After the division, we end up with 210489.3155 and a remainder of 0.0014.
