We're dividing 90479378 by 289 
The aim is to understand the frequency of 289 in 90479378.

Advancing to step 1:
289 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 289

Let's proceed to step 2:
The number 289 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Grab the next digit (4) from the dividend, add it to 90, then carry on: 904 / 289

On to step 3:
If we divide 904 by 289, we get 3 and a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 867 from 904 and we're left with 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 289

Moving on to step 4:
289 can be fit into 377 1 times, resulting in a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 289 from 377 and we're left with 88.
Fetch the next digit (9) from the dividend, attach it to 88 and continue: 889 / 289

Advancing to step 5:
889 divided by 289 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 313.0
Subtract 867 from 889 to get 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 289

Step 6:
The number 289 fits into 223 0 times, leaving a remainder of 223.
Put 0 as the next digit of the answer. 
Result so far: 3130.0
If we take 0 away from 223, we end up with 223.
Fetch the next digit (7) from the dividend, attach it to 223 and continue: 2237 / 289

On to step 7:
The number 289 fits into 2237 7 times, leaving a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 31307.0
Subtracting 2023 from 2237 leaves us with 214.
Append the next digit (8) from the dividend to 214 and continue with: 2148 / 289

Step 8:
2148 divided by 289 is 7 with a remainder of 125.
Use 7 as the next digit of our solution. 
Result so far: 313077.0
If we subtract 2023 from 2148, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
289 can be fit into 1250 4 times, resulting in a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 313077.4
If we subtract 1156 from 1250, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
289 can be fit into 940 3 times, resulting in a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 313077.43
Subtract 867 from 940 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 11:
730 divided by 289 is 2 with a remainder of 152.
The next digit of our result is 2. 
Result so far: 313077.432
If we take 578 away from 730, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
The number 289 fits into 1520 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 313077.4325
If we subtract 1445 from 1520, we get 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 13:
289 can be fit into 750 2 times, resulting in a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 313077.43252
Deduct 578 from 750 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 14:
The number 289 fits into 1720 5 times, leaving a remainder of 275.
The next digit of our result is 5. 
Result so far: 313077.432525
The remainder is 275 after subtracting 1445 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 15:
The number 289 fits into 2750 9 times, leaving a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 313077.4325259
If we subtract 2601 from 2750, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 16:
289 can be fit into 1490 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 313077.43252595
If we take 1445 away from 1490, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 313077.43252595 with a remaining 4.5e-08.
