631405 ÷ 79 
We want to divide 631405 by 79.

Advancing to step 1:
6 divided by 79 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 79

Let's proceed to step 2:
The number 79 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 79

Step 3:
79 can be fit into 631 7 times, resulting in a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 78 after subtracting 553 from 631.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 79

Step 4:
784 divided by 79 is 9 with a remainder of 73.
The next digit of our result is 9. 
Result so far: 79.0
The remainder is 73 after subtracting 711 from 784.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 79

Step 5:
730 divided by 79 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 799.0
Subtract 711 from 730 to get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 79

On to step 6:
When dividing 195 by 79, we get 2 with a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 7992.0
If we take 158 away from 195, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
If we divide 370 by 79, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 7992.4
If we take 316 away from 370, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
The number 79 fits into 540 6 times, leaving a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 7992.46
Deduct 474 from 540 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
If we divide 660 by 79, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 7992.468
Deduct 632 from 660 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
79 can be fit into 280 3 times, resulting in a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 7992.4683
Subtract 237 from 280 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 11:
79 goes into 430 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 7992.46835
If we subtract 395 from 430, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
When dividing 350 by 79, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 7992.468354
The remainder is 34 after subtracting 316 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
When dividing 340 by 79, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 7992.4683544
If we subtract 316 from 340, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 7992.4683544 and a remainder of 2.4e-07.
