We're dividing 90019115 by 283 
The aim is to understand the frequency of 283 in 90019115.

Step 1:
283 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 283

Going ahead to step 2:
If we divide 90 by 283, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 283

On to step 3:
When dividing 900 by 283, we get 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 849 away from 900, we end up with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 283

On to step 4:
511 divided by 283 is 1 with a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 228 after subtracting 283 from 511.
Append the next digit (9) from the dividend to 228 and continue with: 2289 / 283

Moving on to step 5:
The number 283 fits into 2289 8 times, leaving a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 318.0
The remainder is 25 after subtracting 2264 from 2289.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 283

Let's proceed to step 6:
251 divided by 283 is 0 with a remainder of 251.
Write down 0 as next digit of the result. 
Result so far: 3180.0
Deduct 0 from 251 and we're left with 251.
Fetch the next digit (1) from the dividend, attach it to 251 and continue: 2511 / 283

On to step 7:
When dividing 2511 by 283, we get 8 with a remainder of 247.
Record the quotient 8 as the next digit in the result. 
Result so far: 31808.0
The remainder is 247 after subtracting 2264 from 2511.
Grab the next digit (5) from the dividend, add it to 247, then carry on: 2475 / 283

Going ahead to step 8:
2475 divided by 283 is 8 with a remainder of 211.
Write down 8 as next digit of the result. 
Result so far: 318088.0
Subtract 2264 from 2475 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 9:
When dividing 2110 by 283, we get 7 with a remainder of 129.
The next digit of our result is 7. 
Result so far: 318088.7
Subtract 1981 from 2110 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 10:
283 goes into 1290 4 times with a remainder of 158.
Put 4 as the next digit of the answer. 
Result so far: 318088.74
Subtracting 1132 from 1290 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 11:
When dividing 1580 by 283, we get 5 with a remainder of 165.
The next digit of our result is 5. 
Result so far: 318088.745
Subtract 1415 from 1580 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 12:
283 goes into 1650 5 times with a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 318088.7455
Subtracting 1415 from 1650 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final outcome is 318088.7455, with a leftover of 0.00235.
