We're dividing 136357 by 42 
Our goal is to divide 136357 by 42.

Going ahead to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 42

Advancing to step 2:
The number 42 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 42

Advancing to step 3:
136 divided by 42 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 126 from 136 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 42

Going ahead to step 4:
42 goes into 103 2 times with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 84 from 103, we get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 42

Moving on to step 5:
If we divide 195 by 42, we get 4 and a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
The remainder is 27 after subtracting 168 from 195.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 42

Let's proceed to step 6:
42 can be fit into 277 6 times, resulting in a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 3246.0
The remainder is 25 after subtracting 252 from 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
42 goes into 250 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 3246.5
Deduct 210 from 250 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 3246.59
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
220 divided by 42 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3246.595
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
42 goes into 100 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 3246.5952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 3246.59523
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
When dividing 340 by 42, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 3246.595238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
When dividing 40 by 42, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3246.595238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
When dividing 400 by 42, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 3246.59523809
If we take 378 away from 400, 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.

The final outcome is 3246.59523809, with a leftover of 2.2e-08.
