We look at the division of 99429063 by 439 
We're looking to find how many times 439 goes into 99429063.

Going ahead to step 1:
When dividing 9 by 439, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 439

Advancing to step 2:
439 can be fit into 99 0 times, resulting in a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Bring next digit (4) of the dividend behind the 99 and repeat the process: 994 / 439

Let's proceed to step 3:
The number 439 fits into 994 2 times, leaving a remainder of 116.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 878 from 994 to get 116.
Append the next digit (2) from the dividend to 116 and continue with: 1162 / 439

On to step 4:
If we divide 1162 by 439, we get 2 and a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 878 from 1162 to get 284.
Fetch the next digit (9) from the dividend, attach it to 284 and continue: 2849 / 439

On to step 5:
439 can be fit into 2849 6 times, resulting in a remainder of 215.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Subtract 2634 from 2849 to get 215.
Include the next digit (0) from the dividend after 215, then repeat: 2150 / 439

Let's proceed to step 6:
2150 divided by 439 is 4 with a remainder of 394.
Use 4 as the next digit of our solution. 
Result so far: 2264.0
If we subtract 1756 from 2150, we get 394.
Grab the next digit (6) from the dividend, add it to 394, then carry on: 3946 / 439

Let's proceed to step 7:
439 goes into 3946 8 times with a remainder of 434.
Put 8 as the next digit of the answer. 
Result so far: 22648.0
If we take 3512 away from 3946, we end up with 434.
Grab the next digit (3) from the dividend, add it to 434, then carry on: 4343 / 439

Going ahead to step 8:
The number 439 fits into 4343 9 times, leaving a remainder of 392.
Use 9 as the next digit of our solution. 
Result so far: 226489.0
The remainder is 392 after subtracting 3951 from 4343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 9:
The number 439 fits into 3920 8 times, leaving a remainder of 408.
The number 8 becomes the next digit in our result. 
Result so far: 226489.8
Deduct 3512 from 3920 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 10:
If we divide 4080 by 439, we get 9 and a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 226489.89
Subtracting 3951 from 4080 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 11:
439 goes into 1290 2 times with a remainder of 412.
Write down 2 as next digit of the result. 
Result so far: 226489.892
Deduct 878 from 1290 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 12:
439 can be fit into 4120 9 times, resulting in a remainder of 169.
Put 9 as the next digit of the answer. 
Result so far: 226489.8929
Subtract 3951 from 4120 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Step 13:
If we divide 1690 by 439, we get 3 and a remainder of 373.
Write down 3 as next digit of the result. 
Result so far: 226489.89293
Subtracting 1317 from 1690 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 14:
439 can be fit into 3730 8 times, resulting in a remainder of 218.
Use 8 as the next digit of our solution. 
Result so far: 226489.892938
Deduct 3512 from 3730 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 15:
If we divide 2180 by 439, we get 4 and a remainder of 424.
Use 4 as the next digit of our solution. 
Result so far: 226489.8929384
The remainder is 424 after subtracting 1756 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 16:
439 goes into 4240 9 times with a remainder of 289.
Use 9 as the next digit of our solution. 
Result so far: 226489.89293849
If we subtract 3951 from 4240, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

After the division, we end up with 226489.89293849 and a remainder of 2.89e-07.
