Let's divide 866202 by 42
We want to divide 866202 by 42.

Step 1:
42 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 42

On to step 2:
42 can be fit into 86 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 84 from 86, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 42

Step 3:
When dividing 26 by 42, we get 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 26, we end up with 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 42

Step 4:
If we divide 262 by 42, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 206.0
Subtract 252 from 262 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 42

Let's proceed to step 5:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2062.0
Subtract 84 from 100 to get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 42

Let's proceed to step 6:
162 divided by 42 is 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 20623.0
Subtracting 126 from 162 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
When dividing 360 by 42, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 20623.8
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.

On to step 8:
When dividing 240 by 42, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 20623.85
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.

Going ahead to step 9:
If we divide 300 by 42, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 20623.857
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:
If we divide 60 by 42, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 20623.8571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 20623.85714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 20623.857142
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.

Step 13:
If we divide 360 by 42, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 20623.8571428
Subtract 336 from 360 to get 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 14:
The number 42 fits into 240 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 20623.85714285
Subtracting 210 from 240 leaves us 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.

The final outcome is 20623.85714285, with a leftover of 3e-08.
