Let's divide 21035469 by 86
Our goal is to divide 21035469 by 86.

On to step 1:
2 divided by 86 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 86

Step 2:
86 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 86

Going ahead to step 3:
210 divided by 86 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 2.0
If we take 172 away from 210, we end up with 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 86

Step 4:
The number 86 fits into 383 4 times, leaving a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 344 away from 383, we end up with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 86

On to step 5:
If we divide 395 by 86, we get 4 and a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 244.0
Subtracting 344 from 395 leaves us with 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 86

Moving on to step 6:
The number 86 fits into 514 5 times, leaving a remainder of 84.
The next digit of our result is 5. 
Result so far: 2445.0
The remainder is 84 after subtracting 430 from 514.
Grab the next digit (6) from the dividend, add it to 84, then carry on: 846 / 86

Moving on to step 7:
The number 86 fits into 846 9 times, leaving a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 24459.0
If we subtract 774 from 846, we get 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 86

Let's proceed to step 8:
When dividing 729 by 86, we get 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 244598.0
The remainder is 41 after subtracting 688 from 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
If we divide 410 by 86, we get 4 and a remainder of 66.
The next digit of our result is 4. 
Result so far: 244598.4
Deduct 344 from 410 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
660 divided by 86 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 244598.47
Subtract 602 from 660 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
580 divided by 86 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 244598.476
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
640 divided by 86 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 244598.4767
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
380 divided by 86 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 244598.47674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 244598.476744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 244598.476744 and a remainder of 1.6e-06.
