We're dividing 115691 by 42 
Our goal is to divide 115691 by 42.

Advancing to step 1:
If we divide 1 by 42, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 42

Going ahead to step 2:
11 divided by 42 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 42

On to step 3:
The number 42 fits into 115 2 times, leaving a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 84 away from 115, we end up with 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 42

Let's proceed to step 4:
When dividing 316 by 42, we get 7 with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 294 from 316 leaves us with 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 42

Moving on to step 5:
If we divide 229 by 42, we get 5 and a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 275.0
If we take 210 away from 229, we end up with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 42

Step 6:
The number 42 fits into 191 4 times, leaving a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 2754.0
Subtract 168 from 191 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
If we divide 230 by 42, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 2754.5
Deduct 210 from 230 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
42 can be fit into 200 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 2754.54
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
320 divided by 42 is 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 2754.547
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
260 divided by 42 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 2754.5476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
80 divided by 42 is 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 2754.54761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
380 divided by 42 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 2754.547619
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2754.547619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
If we divide 200 by 42, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 2754.54761904
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 2754.54761904 and a remainder of 3.2e-08.
