We look at the division of 371864 by 42 
We want to figure out the number of times 371864 can be divided by 42.

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
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 42

Going ahead to step 2:
42 can be fit into 37 0 times, resulting in a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 42

On to step 3:
371 divided by 42 is 8 with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 336 from 371 and we're left with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 42

Step 4:
The number 42 fits into 358 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we take 336 away from 358, we end up with 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 42

Advancing to step 5:
42 goes into 226 5 times with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 885.0
Deduct 210 from 226 and we're left with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 42

Moving on to step 6:
42 goes into 164 3 times with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 8853.0
Subtracting 126 from 164 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.

On to step 7:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 8853.9
The remainder is 2 after subtracting 378 from 380.
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 8:
20 divided by 42 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8853.9
Deduct 0 from 20 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.

Step 9:
If we divide 200 by 42, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 8853.904
If we take 168 away from 200, we end up 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.

Going ahead to step 10:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 8853.9047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
42 goes into 260 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 8853.90476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
If we divide 80 by 42, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 8853.904761
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.

Step 13:
When dividing 380 by 42, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 8853.9047619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
42 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8853.9047619
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 8853.9047619, with a leftover of 2e-08.
