We look at the division of 420572 by 79 
We want to figure out the number of times 420572 can be divided by 79.

Let's proceed to step 1:
4 divided by 79 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 79

Advancing to step 2:
79 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 79

Step 3:
79 can be fit into 420 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 395 from 420, we get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 79

Let's proceed to step 4:
255 divided by 79 is 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 53.0
If we take 237 away from 255, we end up with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 79

Going ahead to step 5:
The number 79 fits into 187 2 times, leaving a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 532.0
Subtracting 158 from 187 leaves us with 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 79

Going ahead to step 6:
79 goes into 292 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 5323.0
Subtracting 237 from 292 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
If we divide 550 by 79, we get 6 and a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 5323.6
If we take 474 away from 550, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 8:
79 goes into 760 9 times with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 5323.69
The remainder is 49 after subtracting 711 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
The number 79 fits into 490 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 5323.696
If we subtract 474 from 490, we get 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 10:
79 goes into 160 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 5323.6962
If we take 158 away from 160, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
79 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5323.6962
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
79 goes into 200 2 times with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 5323.696202
Subtract 158 from 200 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
When dividing 420 by 79, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5323.6962025
If we subtract 395 from 420, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
79 goes into 250 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 5323.69620253
Subtract 237 from 250 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 5323.69620253 with a remainder of 1.3e-08.
