We look at the division of 667971 by 79 
We want to divide 667971 by 79.

Step 1:
79 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 79

Advancing to step 2:
If we divide 66 by 79, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 79

Going ahead to step 3:
667 divided by 79 is 8 with a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 632 from 667 and we're left with 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 79

Moving on to step 4:
79 goes into 359 4 times with a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Deduct 316 from 359 and we're left with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 79

Moving on to step 5:
When dividing 437 by 79, we get 5 with a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 845.0
If we take 395 away from 437, we end up with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 79

Let's proceed to step 6:
When dividing 421 by 79, we get 5 with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 8455.0
If we take 395 away from 421, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
When dividing 260 by 79, we get 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 8455.3
Deduct 237 from 260 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
The number 79 fits into 230 2 times, leaving a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 8455.32
Deduct 158 from 230 and we're left with 72.
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 9:
720 divided by 79 is 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 8455.329
Subtract 711 from 720 to get 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 10:
79 goes into 90 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 8455.3291
Subtract 79 from 90 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
79 goes into 110 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 8455.32911
Subtract 79 from 110 to get 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 8455.32911 with a balance of 3.1e-05.
