638510 ÷ 79 
We're looking to find how many times 79 goes into 638510.

Moving on to step 1:
79 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 79

Step 2:
When dividing 63 by 79, we get 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 79

Let's proceed to step 3:
When dividing 638 by 79, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 632 from 638 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 79

On to step 4:
79 can be fit into 65 0 times, resulting in a remainder of 65.
The next digit of our result is 0. 
Result so far: 80.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 79

Advancing to step 5:
The number 79 fits into 651 8 times, leaving a remainder of 19.
The next digit of our result is 8. 
Result so far: 808.0
Subtracting 632 from 651 leaves us with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 79

Moving on to step 6:
When dividing 190 by 79, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 8082.0
If we subtract 158 from 190, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
79 can be fit into 320 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 8082.4
Deduct 316 from 320 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 79, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8082.4
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
79 can be fit into 400 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8082.405
Subtracting 395 from 400 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
If we divide 50 by 79, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 8082.405
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
When dividing 500 by 79, we get 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 8082.40506
The remainder is 26 after subtracting 474 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
79 can be fit into 260 3 times, resulting in a remainder of 23.
The next digit of our result is 3. 
Result so far: 8082.405063
The remainder is 23 after subtracting 237 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
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: 8082.4050632
If we subtract 158 from 230, we get 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 14:
If we divide 720 by 79, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 8082.40506329
If we take 711 away from 720, we end up 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.

In conclusion, the division gives 8082.40506329 with a balance of 9e-09.
