We're dividing 40195129 by 342 
Let's see how many times 342 fits into 40195129.

Going ahead to step 1:
The number 342 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 342

On to step 2:
342 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 342

Going ahead to step 3:
401 divided by 342 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 342 from 401 leaves us with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 342

On to step 4:
When dividing 599 by 342, we get 1 with a remainder of 257.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 342 from 599 to get 257.
Grab the next digit (5) from the dividend, add it to 257, then carry on: 2575 / 342

Advancing to step 5:
2575 divided by 342 is 7 with a remainder of 181.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we take 2394 away from 2575, we end up with 181.
Append the next digit (1) from the dividend to 181 and continue with: 1811 / 342

Moving on to step 6:
342 goes into 1811 5 times with a remainder of 101.
The next digit of our result is 5. 
Result so far: 1175.0
Subtract 1710 from 1811 to get 101.
Append the next digit (2) from the dividend to 101 and continue with: 1012 / 342

Going ahead to step 7:
When dividing 1012 by 342, we get 2 with a remainder of 328.
The number 2 becomes the next digit in our result. 
Result so far: 11752.0
Deduct 684 from 1012 and we're left with 328.
Append the next digit (9) from the dividend to 328 and continue with: 3289 / 342

Advancing to step 8:
342 goes into 3289 9 times with a remainder of 211.
The next digit of our result is 9. 
Result so far: 117529.0
Subtract 3078 from 3289 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 9:
2110 divided by 342 is 6 with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 117529.6
Deduct 2052 from 2110 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
342 can be fit into 580 1 times, resulting in a remainder of 238.
Write down 1 as next digit of the result. 
Result so far: 117529.61
The remainder is 238 after subtracting 342 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 11:
342 goes into 2380 6 times with a remainder of 328.
Use 6 as the next digit of our solution. 
Result so far: 117529.616
If we take 2052 away from 2380, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 12:
3280 divided by 342 is 9 with a remainder of 202.
The number 9 becomes the next digit in our result. 
Result so far: 117529.6169
If we subtract 3078 from 3280, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 13:
When dividing 2020 by 342, we get 5 with a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 117529.61695
The remainder is 310 after subtracting 1710 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 14:
342 goes into 3100 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 117529.616959
If we take 3078 away from 3100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 15:
220 divided by 342 is 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 117529.616959
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
When dividing 2200 by 342, we get 6 with a remainder of 148.
Record the quotient 6 as the next digit in the result. 
Result so far: 117529.61695906
Subtract 2052 from 2200 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final outcome is 117529.61695906, with a leftover of 1.48e-07.
