We divide 155688 by 42
We're looking to find how many times 42 goes into 155688.

Advancing to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 42

Advancing to step 2:
When dividing 15 by 42, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 42

Let's proceed to step 3:
When dividing 155 by 42, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 126 from 155 leaves us with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 42

Let's proceed to step 4:
If we divide 296 by 42, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 294 from 296, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 42

Step 5:
The number 42 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 370.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 42

Let's proceed to step 6:
The number 42 fits into 288 6 times, leaving a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 3706.0
The remainder is 36 after subtracting 252 from 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
360 divided by 42 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 3706.8
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
240 divided by 42 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 3706.85
If we subtract 210 from 240, we 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.

Step 9:
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: 3706.857
Deduct 294 from 300 and we're left 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.

Moving on to step 10:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 3706.8571
If we take 42 away from 60, we end up 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.

Moving on to step 11:
42 goes into 180 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 3706.85714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 42, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 3706.857142
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.

Advancing to step 13:
If we divide 360 by 42, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 3706.8571428
Deduct 336 from 360 and we're left 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.

Advancing to step 14:
240 divided by 42 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 3706.85714285
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.

After the division, we end up with 3706.85714285 and a remainder of 3e-08.
