Let's divide 843639 by 79
We want to figure out the number of times 843639 can be divided by 79.

Step 1:
The number 79 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 79

Step 2:
When dividing 84 by 79, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 79 from 84 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 79

Step 3:
The number 79 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 53 to get 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 79

Step 4:
79 can be fit into 536 6 times, resulting in a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
The remainder is 62 after subtracting 474 from 536.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 79

On to step 5:
623 divided by 79 is 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 1067.0
The remainder is 70 after subtracting 553 from 623.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 79

Moving on to step 6:
When dividing 709 by 79, we get 8 with a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 10678.0
Subtracting 632 from 709 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 7:
The number 79 fits into 770 9 times, leaving a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 10678.9
The remainder is 59 after subtracting 711 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 8:
When dividing 590 by 79, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 10678.97
Subtract 553 from 590 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
370 divided by 79 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 10678.974
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.

Going ahead to step 10:
If we divide 540 by 79, we get 6 and a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 10678.9746
If we take 474 away from 540, we end up 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 11:
The number 79 fits into 660 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 10678.97468
If we take 632 away from 660, we end up 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.

On to step 12:
79 goes into 280 3 times with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 10678.974683
Subtracting 237 from 280 leaves us with 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 13:
If we divide 430 by 79, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 10678.9746835
Subtract 395 from 430 to 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.

Going ahead to step 14:
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: 10678.97468354
Deduct 316 from 350 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 10678.97468354 with a remaining 3.4e-08.
