We're dividing 420760 by 42 
We want to figure out the number of times 420760 can be divided by 42.

Let's proceed to step 1:
42 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 42

Moving on to step 2:
When dividing 42 by 42, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 42 from 42 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 42

Going ahead to step 3:
0 divided by 42 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 0, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 42

Going ahead to step 4:
7 divided by 42 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 42

Step 5:
42 can be fit into 76 1 times, resulting in a remainder of 34.
The next digit of our result is 1. 
Result so far: 1001.0
The remainder is 34 after subtracting 42 from 76.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 42

Going ahead to step 6:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10018.0
If we take 336 away from 340, we end up 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 7:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10018.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
If we divide 400 by 42, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 10018.09
If we subtract 378 from 400, we 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.

Let's proceed to step 9:
If we divide 220 by 42, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 10018.095
Deduct 210 from 220 and we're left 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.

Going ahead to step 10:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 10018.0952
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.

Advancing to step 11:
If we divide 160 by 42, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 10018.09523
If we subtract 126 from 160, we get 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 12:
42 goes into 340 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 10018.095238
Deduct 336 from 340 and we're left 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.

Step 13:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10018.095238
If we take 0 away from 40, we end up 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 14:
42 goes into 400 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 10018.09523809
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.

Our division results in 10018.09523809 with a remaining 2.2e-08.
