We're dividing 99298529 by 421 
Our goal is to divide 99298529 by 421.

Let's proceed to step 1:
9 divided by 421 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 421

Let's proceed to step 2:
When dividing 99 by 421, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (2) from the dividend, add it to 99, then carry on: 992 / 421

Advancing to step 3:
421 goes into 992 2 times with a remainder of 150.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 842 away from 992, we end up with 150.
Fetch the next digit (9) from the dividend, attach it to 150 and continue: 1509 / 421

Advancing to step 4:
The number 421 fits into 1509 3 times, leaving a remainder of 246.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 1263 from 1509 to get 246.
Include the next digit (8) from the dividend after 246, then repeat: 2468 / 421

Moving on to step 5:
The number 421 fits into 2468 5 times, leaving a remainder of 363.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
Subtract 2105 from 2468 to get 363.
Fetch the next digit (5) from the dividend, attach it to 363 and continue: 3635 / 421

On to step 6:
421 goes into 3635 8 times with a remainder of 267.
Use 8 as the next digit of our solution. 
Result so far: 2358.0
Deduct 3368 from 3635 and we're left with 267.
Grab the next digit (2) from the dividend, add it to 267, then carry on: 2672 / 421

Advancing to step 7:
The number 421 fits into 2672 6 times, leaving a remainder of 146.
Write down 6 as next digit of the result. 
Result so far: 23586.0
If we take 2526 away from 2672, we end up with 146.
Fetch the next digit (9) from the dividend, attach it to 146 and continue: 1469 / 421

On to step 8:
The number 421 fits into 1469 3 times, leaving a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 235863.0
Subtract 1263 from 1469 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 9:
When dividing 2060 by 421, we get 4 with a remainder of 376.
Write down 4 as next digit of the result. 
Result so far: 235863.4
If we subtract 1684 from 2060, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 10:
3760 divided by 421 is 8 with a remainder of 392.
The next digit of our result is 8. 
Result so far: 235863.48
Subtracting 3368 from 3760 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 11:
421 can be fit into 3920 9 times, resulting in a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 235863.489
Subtract 3789 from 3920 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 12:
1310 divided by 421 is 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 235863.4893
If we take 1263 away from 1310, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 13:
421 can be fit into 470 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 235863.48931
If we take 421 away from 470, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 14:
When dividing 490 by 421, we get 1 with a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 235863.489311
If we take 421 away from 490, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final outcome is 235863.489311, with a leftover of 6.9e-06.
