420535 ÷ 79 
We're looking to find how many times 79 goes into 420535.

Let's proceed to step 1:
If we divide 4 by 79, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 79

On to step 2:
79 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 79

Let's proceed to step 3:
When dividing 420 by 79, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 395 from 420, we get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 79

Going ahead to step 4:
If we divide 255 by 79, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we take 237 away from 255, we end up with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 79

Advancing to step 5:
If we divide 183 by 79, we get 2 and a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 532.0
If we take 158 away from 183, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 79

On to step 6:
79 can be fit into 255 3 times, resulting in a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 5323.0
If we subtract 237 from 255, we 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.

On to step 7:
The number 79 fits into 180 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 5323.2
Deduct 158 from 180 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.

Step 8:
220 divided by 79 is 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 5323.22
Deduct 158 from 220 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 5323.22 and a remainder of 0.062.
