We're dividing 845241 by 86 
We want to divide 845241 by 86.

Step 1:
If we divide 8 by 86, we get 0 and 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.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 86

Moving on to step 2:
The number 86 fits into 84 0 times, leaving a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Fetch the next digit (5) from the dividend, attach it to 84 and continue: 845 / 86

Going ahead to step 3:
845 divided by 86 is 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 774 from 845 leaves us with 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 86

Step 4:
86 goes into 712 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we take 688 away from 712, we end up with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 86

Step 5:
If we divide 244 by 86, we get 2 and a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 982.0
Deduct 172 from 244 and we're left with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 86

On to step 6:
The number 86 fits into 721 8 times, leaving a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 9828.0
Subtract 688 from 721 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
The number 86 fits into 330 3 times, leaving a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 9828.3
If we take 258 away from 330, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
720 divided by 86 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 9828.38
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
86 goes into 320 3 times with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 9828.383
Subtract 258 from 320 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
If we divide 620 by 86, we get 7 and a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 9828.3837
Deduct 602 from 620 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
If we divide 180 by 86, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 9828.38372
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
The number 86 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 9828.38372
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
86 goes into 800 9 times with a remainder of 26.
The next digit of our result is 9. 
Result so far: 9828.3837209
Subtracting 774 from 800 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
260 divided by 86 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 9828.38372093
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 9828.38372093 and a remainder of 2e-09.
