91603 ÷ 83 
We're looking to find how many times 83 goes into 91603.

On to step 1:
When dividing 9 by 83, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 83

On to step 2:
83 goes into 91 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 83 from 91, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 83

Going ahead to step 3:
The number 83 fits into 86 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 83 from 86 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 83

Going ahead to step 4:
When dividing 30 by 83, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 110.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 83

Step 5:
When dividing 303 by 83, we get 3 with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 1103.0
If we take 249 away from 303, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 6:
83 can be fit into 540 6 times, resulting in a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 1103.6
Deduct 498 from 540 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
83 goes into 420 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1103.65
The remainder is 5 after subtracting 415 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
83 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1103.65
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.

Let's proceed to step 9:
500 divided by 83 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 1103.6506
The remainder is 2 after subtracting 498 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
83 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1103.6506
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
83 can be fit into 200 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 1103.650602
If we subtract 166 from 200, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
The number 83 fits into 340 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1103.6506024
Subtract 332 from 340 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
If we divide 80 by 83, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 1103.6506024
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 1103.6506024 with a remainder of 8e-08.
