We divide 509564 by 83
The aim is to understand the frequency of 83 in 509564.

Going ahead to step 1:
5 divided by 83 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 83

Moving on to step 2:
The number 83 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 83

Going ahead to step 3:
83 can be fit into 509 6 times, resulting in a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 498 from 509 and we're left with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 83

Moving on to step 4:
83 can be fit into 115 1 times, resulting in a remainder of 32.
The next digit of our result is 1. 
Result so far: 61.0
Deduct 83 from 115 and we're left with 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 83

Going ahead to step 5:
If we divide 326 by 83, we get 3 and a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 613.0
Subtracting 249 from 326 leaves us with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 83

Advancing to step 6:
When dividing 774 by 83, we get 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 6139.0
Deduct 747 from 774 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
83 can be fit into 270 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 6139.3
Subtract 249 from 270 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
83 can be fit into 210 2 times, resulting in a remainder of 44.
The next digit of our result is 2. 
Result so far: 6139.32
Deduct 166 from 210 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
83 can be fit into 440 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 6139.325
Subtracting 415 from 440 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.

Going ahead to step 10:
83 can be fit into 250 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 6139.3253
If we take 249 away from 250, we end up 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.

Step 11:
83 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 6139.3253
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 83, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 6139.325301
If we take 83 away from 100, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
170 divided by 83 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6139.3253012
If we take 166 away from 170, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
83 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6139.3253012
If we take 0 away from 40, we end up 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.

The final outcome is 6139.3253012, with a leftover of 4e-08.
