We're dividing 3995400 by 429 
We're looking to find how many times 429 goes into 3995400.

Moving on to step 1:
429 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 429

Going ahead to step 2:
When dividing 39 by 429, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 429

Advancing to step 3:
429 can be fit into 399 0 times, resulting in a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 399, we end up with 399.
Include the next digit (5) from the dividend after 399, then repeat: 3995 / 429

Advancing to step 4:
The number 429 fits into 3995 9 times, leaving a remainder of 134.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 3861 from 3995, we get 134.
Append the next digit (4) from the dividend to 134 and continue with: 1344 / 429

Let's proceed to step 5:
If we divide 1344 by 429, we get 3 and a remainder of 57.
The next digit of our result is 3. 
Result so far: 93.0
Subtracting 1287 from 1344 leaves us with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 429

On to step 6:
429 goes into 570 1 times with a remainder of 141.
Use 1 as the next digit of our solution. 
Result so far: 931.0
Subtracting 429 from 570 leaves us with 141.
Include the next digit (0) from the dividend after 141, then repeat: 1410 / 429

On to step 7:
When dividing 1410 by 429, we get 3 with a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 9313.0
Subtract 1287 from 1410 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 8:
When dividing 1230 by 429, we get 2 with a remainder of 372.
Use 2 as the next digit of our solution. 
Result so far: 9313.2
Subtracting 858 from 1230 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 9:
When dividing 3720 by 429, we get 8 with a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 9313.28
Subtracting 3432 from 3720 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 10:
2880 divided by 429 is 6 with a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 9313.286
If we take 2574 away from 2880, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 11:
429 can be fit into 3060 7 times, resulting in a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 9313.2867
Deduct 3003 from 3060 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 12:
If we divide 570 by 429, we get 1 and a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 9313.28671
Deduct 429 from 570 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 13:
429 goes into 1410 3 times with a remainder of 123.
Write down 3 as next digit of the result. 
Result so far: 9313.286713
The remainder is 123 after subtracting 1287 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 14:
1230 divided by 429 is 2 with a remainder of 372.
Use 2 as the next digit of our solution. 
Result so far: 9313.2867132
Deduct 858 from 1230 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 15:
429 goes into 3720 8 times with a remainder of 288.
The next digit of our result is 8. 
Result so far: 9313.28671328
The remainder is 288 after subtracting 3432 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 9313.28671328, with a leftover of 2.88e-07.
