83111139 divided by 204 
The aim is to understand the frequency of 204 in 83111139.

Let's proceed to step 1:
204 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 204

On to step 2:
When dividing 83 by 204, we get 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 204

Moving on to step 3:
204 can be fit into 831 4 times, resulting in a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 816 from 831 leaves us with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 204

Going ahead to step 4:
204 goes into 151 0 times with a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 151 and we're left with 151.
Append the next digit (1) from the dividend to 151 and continue with: 1511 / 204

Advancing to step 5:
1511 divided by 204 is 7 with a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
The remainder is 83 after subtracting 1428 from 1511.
Include the next digit (1) from the dividend after 83, then repeat: 831 / 204

Advancing to step 6:
204 goes into 831 4 times with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4074.0
Deduct 816 from 831 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 204

On to step 7:
When dividing 153 by 204, we get 0 with a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 40740.0
Deduct 0 from 153 and we're left with 153.
Take the next digit (9) from the dividend and append it to 153, then repeat: 1539 / 204

Let's proceed to step 8:
If we divide 1539 by 204, we get 7 and a remainder of 111.
Use 7 as the next digit of our solution. 
Result so far: 407407.0
The remainder is 111 after subtracting 1428 from 1539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 9:
1110 divided by 204 is 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 407407.5
If we subtract 1020 from 1110, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
If we divide 900 by 204, we get 4 and a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 407407.54
The remainder is 84 after subtracting 816 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
When dividing 840 by 204, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 407407.544
Subtract 816 from 840 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 407407.544 with a remainder of 0.0024.
