331935 ÷ 42 
Our goal is to divide 331935 by 42.

On to step 1:
42 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 42

Let's proceed to step 2:
When dividing 33 by 42, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 42

Advancing to step 3:
When dividing 331 by 42, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 294 from 331 and we're left with 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 42

Advancing to step 4:
When dividing 379 by 42, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtract 378 from 379 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 42

Advancing to step 5:
42 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 790.0
If we subtract 0 from 13, we get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 42

Advancing to step 6:
The number 42 fits into 135 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 7903.0
Subtracting 126 from 135 leaves us 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.

Let's proceed to step 7:
If we divide 90 by 42, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 7903.2
If we subtract 84 from 90, we get 6.
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 8:
When dividing 60 by 42, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 7903.21
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.

Going ahead to step 9:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 7903.214
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 10:
42 goes into 120 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 7903.2142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
360 divided by 42 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 7903.21428
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.

On to step 12:
If we divide 240 by 42, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 7903.214285
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
When dividing 300 by 42, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7903.2142857
Subtracting 294 from 300 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.

Going ahead to step 14:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 7903.21428571
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.

The quotient of the division is 7903.21428571, and the remainder is 1.8e-08.
