We look at the division of 801852 by 42 
We want to figure out the number of times 801852 can be divided by 42.

Moving on to 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.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 42

Step 2:
When dividing 80 by 42, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 42 from 80 to get 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 42

Advancing to step 3:
42 goes into 381 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 378 away from 381, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 42

Step 4:
The number 42 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 42

Step 5:
The number 42 fits into 385 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 1909.0
Subtracting 378 from 385 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 42

Going ahead to step 6:
When dividing 72 by 42, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 19091.0
If we take 42 away from 72, we end up 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.

Going ahead to step 7:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 19091.7
Subtracting 294 from 300 leaves us 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.

Step 8:
When dividing 60 by 42, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 19091.71
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 19091.714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 19091.7142
Deduct 84 from 120 and we're left 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 11:
When dividing 360 by 42, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 19091.71428
If we take 336 away from 360, we end up 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 12:
When dividing 240 by 42, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 19091.714285
If we subtract 210 from 240, we get 30.
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 13:
42 goes into 300 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 19091.7142857
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.

Let's proceed to step 14:
If we divide 60 by 42, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 19091.71428571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 19091.71428571 with a remaining 1.8e-08.
