452103 ÷ 83 
We want to figure out the number of times 452103 can be divided by 83.

Step 1:
The number 83 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 83

On to step 2:
83 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 83

Moving on to step 3:
When dividing 452 by 83, we get 5 with a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 415 from 452 to get 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 83

On to step 4:
371 divided by 83 is 4 with a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we subtract 332 from 371, we get 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 83

Advancing to step 5:
390 divided by 83 is 4 with a remainder of 58.
The next digit of our result is 4. 
Result so far: 544.0
The remainder is 58 after subtracting 332 from 390.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 83

On to step 6:
When dividing 583 by 83, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 5447.0
Subtracting 581 from 583 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 83 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 5447.0
If we take 0 away from 20, we end up with 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 8:
83 goes into 200 2 times with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 5447.02
The remainder is 34 after subtracting 166 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
83 goes into 340 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 5447.024
Subtracting 332 from 340 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
83 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 5447.024
Subtracting 0 from 80 leaves us 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.

Moving on to step 11:
If we divide 800 by 83, we get 9 and a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 5447.02409
Subtract 747 from 800 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
When dividing 530 by 83, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 5447.024096
If we subtract 498 from 530, 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.

Step 13:
320 divided by 83 is 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 5447.0240963
The remainder is 71 after subtracting 249 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 14:
83 can be fit into 710 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 5447.02409638
Subtracting 664 from 710 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 5447.02409638 with a remainder of 4.6e-08.
