903948 divided by 83 
We want to figure out the number of times 903948 can be divided by 83.

Going ahead to step 1:
9 divided by 83 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 83

Advancing to step 2:
83 can be fit into 90 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
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

Let's proceed to step 3:
83 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 73 and we're left with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 83

Step 4:
739 divided by 83 is 8 with a remainder of 75.
Use 8 as the next digit of our solution. 
Result so far: 108.0
If we take 664 away from 739, we end up with 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 83

Step 5:
754 divided by 83 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1089.0
Deduct 747 from 754 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 83

Moving on to step 6:
83 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 10890.0
The remainder is 78 after subtracting 0 from 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
If we divide 780 by 83, we get 9 and a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 10890.9
Subtract 747 from 780 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 8:
The number 83 fits into 330 3 times, leaving a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 10890.93
If we take 249 away from 330, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
The number 83 fits into 810 9 times, leaving a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 10890.939
Deduct 747 from 810 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 10:
If we divide 630 by 83, we get 7 and a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 10890.9397
Subtracting 581 from 630 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 11:
The number 83 fits into 490 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 10890.93975
Subtracting 415 from 490 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
When dividing 750 by 83, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 10890.939759
If we take 747 away from 750, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
When dividing 30 by 83, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10890.939759
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
83 can be fit into 300 3 times, resulting in a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 10890.93975903
Subtracting 249 from 300 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 10890.93975903, with a leftover of 5.1e-08.
