We divide 421172 by 79
We're looking to find how many times 79 goes into 421172.

Advancing to step 1:
79 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 79

Going ahead to step 2:
If we divide 42 by 79, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 79

Let's proceed to step 3:
If we divide 421 by 79, we get 5 and a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 26 after subtracting 395 from 421.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 79

Step 4:
79 goes into 261 3 times with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Deduct 237 from 261 and we're left with 24.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 79

Going ahead to step 5:
If we divide 247 by 79, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 533.0
If we subtract 237 from 247, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 79

On to step 6:
102 divided by 79 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 5331.0
Subtract 79 from 102 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
The number 79 fits into 230 2 times, leaving a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 5331.2
The remainder is 72 after subtracting 158 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
The number 79 fits into 720 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 5331.29
Subtracting 711 from 720 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
90 divided by 79 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 5331.291
Deduct 79 from 90 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
When dividing 110 by 79, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 5331.2911
Deduct 79 from 110 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

In conclusion, the division gives 5331.2911 with a balance of 0.00031.
