On to step 4:
429 can be fit into 4093 9 times, resulting in a remainder of 232.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 3861 away from 4093, we end up with 232.
Append the next digit (5) from the dividend to 232 and continue with: 2325 / 429

On to step 5:
The number 429 fits into 2325 5 times, leaving a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 95.0
The remainder is 180 after subtracting 2145 from 2325.
Include the next digit (0) from the dividend after 180, then repeat: 1800 / 429

Let's proceed to step 6:
429 goes into 1800 4 times with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 954.0
If we take 1716 away from 1800, we end up with 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 429

Going ahead to step 7:
429 can be fit into 848 1 times, resulting in a remainder of 419.
Use 1 as the next digit of our solution. 
Result so far: 9541.0
Deduct 429 from 848 and we're left with 419.
Include the next digit (9) from the dividend after 419, then repeat: 4199 / 429

Step 8:
429 goes into 4199 9 times with a remainder of 338.
Put 9 as the next digit of the answer. 
Result so far: 95419.0
If we subtract 3861 from 4199, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
3380 divided by 429 is 7 with a remainder of 377.
Record the quotient 7 as the next digit in the result. 
Result so far: 95419.7
If we take 3003 away from 3380, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 10:
If we divide 3770 by 429, we get 8 and a remainder of 338.
Write down 8 as next digit of the result. 
Result so far: 95419.78
Subtract 3432 from 3770 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 11:
If we divide 3380 by 429, we get 7 and a remainder of 377.
The number 7 becomes the next digit in our result. 
Result so far: 95419.787
Subtracting 3003 from 3380 leaves us with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Let's proceed to step 12:
429 goes into 3770 8 times with a remainder of 338.
The number 8 becomes the next digit in our result. 
Result so far: 95419.7878
If we subtract 3432 from 3770, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 13:
When dividing 3380 by 429, we get 7 with a remainder of 377.
Write down 7 as next digit of the result. 
Result so far: 95419.78787
If we take 3003 away from 3380, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 14:
429 goes into 3770 8 times with a remainder of 338.
The next digit of our result is 8. 
Result so far: 95419.787878
Subtract 3432 from 3770 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 15:
429 can be fit into 3380 7 times, resulting in a remainder of 377.
Put 7 as the next digit of the answer. 
Result so far: 95419.7878787
If we subtract 3003 from 3380, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 16:
3770 divided by 429 is 8 with a remainder of 338.
The next digit of our result is 8. 
Result so far: 95419.78787878
The remainder is 338 after subtracting 3432 from 3770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

After the division, we end up with 95419.78787878 and a remainder of 3.38e-07.
