409603 ÷ 83 
We want to figure out the number of times 409603 can be divided by 83.

Going ahead to step 1:
4 divided by 83 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 83

On to step 2:
If we divide 40 by 83, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 83

Moving on to step 3:
83 can be fit into 409 4 times, resulting in a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 332 from 409, we get 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 83

Advancing to step 4:
83 can be fit into 776 9 times, resulting in a remainder of 29.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 747 from 776, we get 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 83

Moving on to step 5:
83 goes into 290 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 493.0
The remainder is 41 after subtracting 249 from 290.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 83

Let's proceed to step 6:
83 can be fit into 413 4 times, resulting in a remainder of 81.
Use 4 as the next digit of our solution. 
Result so far: 4934.0
Deduct 332 from 413 and we're left 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 7:
83 goes into 810 9 times with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 4934.9
Subtract 747 from 810 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 8:
When dividing 630 by 83, we get 7 with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 4934.97
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.

Advancing to step 9:
490 divided by 83 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 4934.975
If we take 415 away from 490, we end up 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 10:
750 divided by 83 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 4934.9759
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.

Step 11:
If we divide 30 by 83, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4934.9759
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.

Moving on to step 12:
When dividing 300 by 83, we get 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 4934.975903
If we subtract 249 from 300, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
When dividing 510 by 83, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 4934.9759036
Subtract 498 from 510 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
When dividing 120 by 83, we get 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 4934.97590361
Deduct 83 from 120 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 4934.97590361 with a remainder of 3.7e-08.
