117181 divided by 42 
We want to divide 117181 by 42.

Step 1:
If we divide 1 by 42, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 42

Step 2:
42 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 42

Going ahead to step 3:
If we divide 117 by 42, we get 2 and a remainder of 33.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 84 from 117 and we're left with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 42

Advancing to step 4:
If we divide 331 by 42, we get 7 and a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 294 from 331 to get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 42

Advancing to step 5:
42 goes into 378 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 279.0
The remainder is 0 after subtracting 378 from 378.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 42

Advancing to step 6:
42 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 2790.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 42 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2790.0
Subtracting 0 from 10 leaves us 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.

Moving on to step 8:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2790.02
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 2790.023
Deduct 126 from 160 and we're left 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.

Step 10:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 2790.0238
Deduct 336 from 340 and we're left 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 11:
When dividing 40 by 42, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 2790.0238
Subtracting 0 from 40 leaves us 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 12:
If we divide 400 by 42, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 2790.023809
If we subtract 378 from 400, we get 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 13:
When dividing 220 by 42, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2790.0238095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
When dividing 100 by 42, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2790.02380952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 2790.02380952 and a remainder of 1.6e-08.
