We're dividing 86643286 by 842 
We want to figure out the number of times 86643286 can be divided by 842.

On to step 1:
If we divide 8 by 842, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 842

Going ahead to step 2:
The number 842 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 842

Moving on to step 3:
842 goes into 866 1 times with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 842 from 866 and we're left with 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 842

Step 4:
842 goes into 244 0 times with a remainder of 244.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 244, we end up with 244.
Grab the next digit (3) from the dividend, add it to 244, then carry on: 2443 / 842

Going ahead to step 5:
842 can be fit into 2443 2 times, resulting in a remainder of 759.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 1684 from 2443 to get 759.
Take the next digit (2) from the dividend and append it to 759, then repeat: 7592 / 842

Let's proceed to step 6:
842 can be fit into 7592 9 times, resulting in a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 1029.0
Deduct 7578 from 7592 and we're left with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 842

On to step 7:
When dividing 148 by 842, we get 0 with a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 10290.0
Deduct 0 from 148 and we're left with 148.
Fetch the next digit (6) from the dividend, attach it to 148 and continue: 1486 / 842

Let's proceed to step 8:
1486 divided by 842 is 1 with a remainder of 644.
Put 1 as the next digit of the answer. 
Result so far: 102901.0
If we take 842 away from 1486, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 9:
If we divide 6440 by 842, we get 7 and a remainder of 546.
Use 7 as the next digit of our solution. 
Result so far: 102901.7
Deduct 5894 from 6440 and we're left with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 10:
5460 divided by 842 is 6 with a remainder of 408.
The next digit of our result is 6. 
Result so far: 102901.76
If we subtract 5052 from 5460, we 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.

Let's proceed to step 11:
4080 divided by 842 is 4 with a remainder of 712.
Record the quotient 4 as the next digit in the result. 
Result so far: 102901.764
Subtracting 3368 from 4080 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Step 12:
If we divide 7120 by 842, we get 8 and a remainder of 384.
Use 8 as the next digit of our solution. 
Result so far: 102901.7648
Deduct 6736 from 7120 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 13:
If we divide 3840 by 842, we get 4 and a remainder of 472.
Record the quotient 4 as the next digit in the result. 
Result so far: 102901.76484
If we take 3368 away from 3840, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 14:
If we divide 4720 by 842, we get 5 and a remainder of 510.
The next digit of our result is 5. 
Result so far: 102901.764845
Deduct 4210 from 4720 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 15:
842 goes into 5100 6 times with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 102901.7648456
Deduct 5052 from 5100 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
If we divide 480 by 842, we get 0 and a remainder of 480.
The next digit of our result is 0. 
Result so far: 102901.7648456
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Our division results in 102901.7648456 with a remaining 4.8e-07.
