We look at the division of 83794 by 42 
We want to figure out the number of times 83794 can be divided by 42.

On to step 1:
8 divided by 42 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 42

Let's proceed to step 2:
The number 42 fits into 83 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 83 and we're left with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 42

Advancing to step 3:
When dividing 417 by 42, we get 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 378 away from 417, we end up with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 42

On to step 4:
When dividing 399 by 42, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 199.0
Deduct 378 from 399 and we're left with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 42

Moving on to step 5:
When dividing 214 by 42, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 1995.0
If we subtract 210 from 214, 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.

On to step 6:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1995.0
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 7:
42 goes into 400 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 1995.09
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1995.095
Subtracting 210 from 220 leaves us 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.

Moving on to step 9:
100 divided by 42 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 1995.0952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 1995.09523
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.

Going ahead to step 11:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 1995.095238
Subtracting 336 from 340 leaves us 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.

Moving on to step 12:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1995.095238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 1995.09523809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 1995.09523809, with a leftover of 2.2e-08.
