361990 divided by 42 
We're looking to find how many times 42 goes into 361990.

Going ahead to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 42

Moving on 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.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 42

Let's proceed to step 3:
361 divided by 42 is 8 with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 336 from 361, we get 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 42

Step 4:
42 goes into 259 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we subtract 252 from 259, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 42

Advancing to step 5:
When dividing 79 by 42, we get 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 861.0
Deduct 42 from 79 and we're left with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 42

Going ahead to step 6:
370 divided by 42 is 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 8618.0
Subtracting 336 from 370 leaves us 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.

Let's proceed to step 7:
42 goes into 340 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 8618.8
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 42, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8618.8
Deduct 0 from 40 and we're left 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.

Advancing to step 9:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 8618.809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
220 divided by 42 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 8618.8095
If we take 210 away from 220, we end up 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.

Step 11:
42 goes into 100 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 8618.80952
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 12:
When dividing 160 by 42, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 8618.809523
Subtracting 126 from 160 leaves us 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.

Moving on to step 13:
If we divide 340 by 42, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 8618.8095238
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.

On to step 14:
42 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8618.8095238
Deduct 0 from 40 and we're left 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.

After the division, we end up with 8618.8095238 and a remainder of 4e-08.
