We look at the division of 856693 by 42 
We want to divide 856693 by 42.

Advancing to step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 42

On to step 2:
When dividing 85 by 42, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 84 away from 85, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 42

Going ahead to step 3:
The number 42 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 42

Step 4:
166 divided by 42 is 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
If we take 126 away from 166, we end up with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 42

Going ahead to step 5:
The number 42 fits into 409 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 2039.0
The remainder is 31 after subtracting 378 from 409.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 42

Advancing to step 6:
42 can be fit into 313 7 times, resulting in a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 20397.0
Deduct 294 from 313 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
When dividing 190 by 42, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 20397.4
Deduct 168 from 190 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.

On to step 8:
The number 42 fits into 220 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 20397.45
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 42, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 20397.452
Deduct 84 from 100 and we're left 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.

Step 10:
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: 20397.4523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
When dividing 340 by 42, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 20397.45238
Subtract 336 from 340 to 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.

Going ahead to step 12:
40 divided by 42 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 20397.45238
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 13:
When dividing 400 by 42, we get 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 20397.4523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
220 divided by 42 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 20397.45238095
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.

The final outcome is 20397.45238095, with a leftover of 1e-08.
