Let's divide 83919 by 8
Let's see how many times 8 fits into 83919.

Moving on to step 1:
8 can be fit into 8 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 8

Step 2:
8 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 8

Going ahead to step 3:
8 goes into 39 4 times with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
The remainder is 7 after subtracting 32 from 39.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 8

Moving on to step 4:
8 goes into 71 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 1048.0
Deduct 64 from 71 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 8

Let's proceed to step 5:
When dividing 79 by 8, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 10489.0
If we subtract 72 from 79, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
The number 8 fits into 70 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 10489.8
Deduct 64 from 70 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 8 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 10489.87
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10489.875
Deduct 40 from 40 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10489.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10489.875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10489.875 with a remaining 0.0.
