We divide 90851827 by 389
The aim is to understand the frequency of 389 in 90851827.

Let's proceed to step 1:
The number 389 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 389

Let's proceed to step 2:
389 can be fit into 90 0 times, resulting in 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.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 389

Going ahead to step 3:
389 can be fit into 908 2 times, resulting in a remainder of 130.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 778 from 908 leaves us with 130.
Include the next digit (5) from the dividend after 130, then repeat: 1305 / 389

On to step 4:
389 can be fit into 1305 3 times, resulting in a remainder of 138.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 1167 from 1305 to get 138.
Append the next digit (1) from the dividend to 138 and continue with: 1381 / 389

Step 5:
389 can be fit into 1381 3 times, resulting in a remainder of 214.
The next digit of our result is 3. 
Result so far: 233.0
If we subtract 1167 from 1381, we get 214.
Bring next digit (8) of the dividend behind the 214 and repeat the process: 2148 / 389

On to step 6:
When dividing 2148 by 389, we get 5 with a remainder of 203.
Use 5 as the next digit of our solution. 
Result so far: 2335.0
The remainder is 203 after subtracting 1945 from 2148.
Grab the next digit (2) from the dividend, add it to 203, then carry on: 2032 / 389

Moving on to step 7:
2032 divided by 389 is 5 with a remainder of 87.
Put 5 as the next digit of the answer. 
Result so far: 23355.0
If we take 1945 away from 2032, we end up with 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 389

Step 8:
When dividing 877 by 389, we get 2 with a remainder of 99.
Use 2 as the next digit of our solution. 
Result so far: 233552.0
Subtracting 778 from 877 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 9:
990 divided by 389 is 2 with a remainder of 212.
Put 2 as the next digit of the answer. 
Result so far: 233552.2
Subtract 778 from 990 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 10:
If we divide 2120 by 389, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 233552.25
Deduct 1945 from 2120 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 11:
If we divide 1750 by 389, we get 4 and a remainder of 194.
Record the quotient 4 as the next digit in the result. 
Result so far: 233552.254
If we subtract 1556 from 1750, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 12:
The number 389 fits into 1940 4 times, leaving a remainder of 384.
The number 4 becomes the next digit in our result. 
Result so far: 233552.2544
Subtracting 1556 from 1940 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

After the division, we end up with 233552.2544 and a remainder of 0.00384.
