Let's divide 86865580 by 422
We want to divide 86865580 by 422.

Moving on to step 1:
The number 422 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 422

Let's proceed to step 2:
422 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 422

Advancing to step 3:
422 can be fit into 868 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 844 from 868 and we're left with 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 422

Moving on to step 4:
422 goes into 246 0 times with a remainder of 246.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 246, we end up with 246.
Append the next digit (5) from the dividend to 246 and continue with: 2465 / 422

Step 5:
The number 422 fits into 2465 5 times, leaving a remainder of 355.
Record the quotient 5 as the next digit in the result. 
Result so far: 205.0
Subtract 2110 from 2465 to get 355.
Take the next digit (5) from the dividend and append it to 355, then repeat: 3555 / 422

Let's proceed to step 6:
3555 divided by 422 is 8 with a remainder of 179.
Put 8 as the next digit of the answer. 
Result so far: 2058.0
Subtract 3376 from 3555 to get 179.
Append the next digit (8) from the dividend to 179 and continue with: 1798 / 422

Let's proceed to step 7:
When dividing 1798 by 422, we get 4 with a remainder of 110.
The number 4 becomes the next digit in our result. 
Result so far: 20584.0
Subtracting 1688 from 1798 leaves us with 110.
Append the next digit (0) from the dividend to 110 and continue with: 1100 / 422

Going ahead to step 8:
When dividing 1100 by 422, we get 2 with a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 205842.0
If we take 844 away from 1100, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 9:
When dividing 2560 by 422, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 205842.6
The remainder is 28 after subtracting 2532 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
The number 422 fits into 280 0 times, leaving a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 205842.6
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 11:
422 goes into 2800 6 times with a remainder of 268.
Write down 6 as next digit of the result. 
Result so far: 205842.606
Subtract 2532 from 2800 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 12:
2680 divided by 422 is 6 with a remainder of 148.
Record the quotient 6 as the next digit in the result. 
Result so far: 205842.6066
Subtract 2532 from 2680 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

After the division, we end up with 205842.6066 and a remainder of 0.00148.
