We look at the division of 361845 by 42 
We want to figure out the number of times 361845 can be divided by 42.

Let's proceed to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 42

Going ahead to step 2:
36 divided by 42 is 0 with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 42

Moving on to step 3:
If we divide 361 by 42, we get 8 and a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 336 from 361 and we're left with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 42

On to step 4:
The number 42 fits into 258 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtracting 252 from 258 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 42

Advancing to step 5:
The number 42 fits into 64 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 861.0
Subtract 42 from 64 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 42

On to step 6:
42 goes into 225 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8615.0
Subtract 210 from 225 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
150 divided by 42 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 8615.3
Subtracting 126 from 150 leaves us 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.

Going ahead to step 8:
When dividing 240 by 42, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8615.35
If we take 210 away from 240, we end up 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 9:
42 goes into 300 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 8615.357
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.

Going ahead to step 10:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 8615.3571
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.

Step 11:
42 goes into 180 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 8615.35714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
If we divide 120 by 42, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 8615.357142
If we subtract 84 from 120, we 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.

Moving on to step 13:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8615.3571428
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.

Let's proceed to step 14:
If we divide 240 by 42, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8615.35714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 8615.35714285, and the remainder is 3e-08.
