Let's divide 857398 by 79
We want to figure out the number of times 857398 can be divided by 79.

On to step 1:
79 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 79

Let's proceed to step 2:
When dividing 85 by 79, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 79 from 85, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 79

Advancing to step 3:
When dividing 67 by 79, we get 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 67 leaves us with 67.
Fetch the next digit (3) from the dividend, attach it to 67 and continue: 673 / 79

Step 4:
673 divided by 79 is 8 with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 108.0
If we take 632 away from 673, we end up with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 79

On to step 5:
79 goes into 419 5 times with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
Subtracting 395 from 419 leaves us with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 79

Moving on to step 6:
248 divided by 79 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 10853.0
If we subtract 237 from 248, we 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.

On to step 7:
The number 79 fits into 110 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 10853.1
If we take 79 away from 110, we end up 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.

Going ahead to step 8:
If we divide 310 by 79, we get 3 and a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 10853.13
Subtract 237 from 310 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
79 can be fit into 730 9 times, resulting in a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 10853.139
Deduct 711 from 730 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
79 goes into 190 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 10853.1392
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.

Going ahead to step 11:
The number 79 fits into 320 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 10853.13924
If we take 316 away from 320, we end up 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.

Step 12:
79 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10853.13924
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
79 can be fit into 400 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 10853.1392405
The remainder is 5 after subtracting 395 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
The number 79 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10853.1392405
Subtracting 0 from 50 leaves us 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.

The final outcome is 10853.1392405, with a leftover of 5e-08.
