Let's divide 183129 by 42
Let's see how many times 42 fits into 183129.

Step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 42

On to step 2:
18 divided by 42 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 42

On to step 3:
If we divide 183 by 42, we get 4 and a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 168 away from 183, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 42

Let's proceed to step 4:
42 goes into 151 3 times with a remainder of 25.
The next digit of our result is 3. 
Result so far: 43.0
If we take 126 away from 151, we end up with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 42

Going ahead to step 5:
When dividing 252 by 42, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 436.0
Subtract 252 from 252 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 42

Let's proceed to step 6:
9 divided by 42 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 4360.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 42 fits into 90 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 4360.2
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
If we divide 60 by 42, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 4360.21
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
When dividing 180 by 42, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4360.214
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
120 divided by 42 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 4360.2142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 4360.21428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
42 goes into 240 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 4360.214285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
If we divide 300 by 42, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 4360.2142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
When dividing 60 by 42, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 4360.21428571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 4360.21428571 and a remainder of 1.8e-08.
