We look at the division of 903978 by 83 
We want to figure out the number of times 903978 can be divided by 83.

Step 1:
When dividing 9 by 83, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 83

On to step 2:
When dividing 90 by 83, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 83 from 90 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 83

On to step 3:
The number 83 fits into 73 0 times, leaving a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 73 to get 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 83

Advancing to step 4:
The number 83 fits into 739 8 times, leaving a remainder of 75.
The next digit of our result is 8. 
Result so far: 108.0
Subtract 664 from 739 to get 75.
Take the next digit (7) from the dividend and append it to 75, then repeat: 757 / 83

Going ahead to step 5:
83 can be fit into 757 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 1089.0
Deduct 747 from 757 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 83

Moving on to step 6:
83 can be fit into 108 1 times, resulting in a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 10891.0
Subtracting 83 from 108 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
The number 83 fits into 250 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 10891.3
Subtracting 249 from 250 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
83 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10891.3
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 83, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 10891.301
The remainder is 17 after subtracting 83 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
83 can be fit into 170 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 10891.3012
Subtract 166 from 170 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 83 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10891.3012
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.

Moving on to step 12:
When dividing 400 by 83, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 10891.301204
Deduct 332 from 400 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 13:
If we divide 680 by 83, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 10891.3012048
If we take 664 away from 680, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
160 divided by 83 is 1 with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 10891.30120481
Deduct 83 from 160 and we're left 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.

The final outcome is 10891.30120481, with a leftover of 7.7e-08.
