90811073 divided by 234 
The aim is to understand the frequency of 234 in 90811073.

Moving on to step 1:
234 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
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 234

On to step 2:
234 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 234

Step 3:
234 goes into 908 3 times with a remainder of 206.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 702 from 908 and we're left with 206.
Take the next digit (1) from the dividend and append it to 206, then repeat: 2061 / 234

Advancing to step 4:
When dividing 2061 by 234, we get 8 with a remainder of 189.
The next digit of our result is 8. 
Result so far: 38.0
If we take 1872 away from 2061, we end up with 189.
Take the next digit (1) from the dividend and append it to 189, then repeat: 1891 / 234

Step 5:
The number 234 fits into 1891 8 times, leaving a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 388.0
The remainder is 19 after subtracting 1872 from 1891.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 234

Going ahead to step 6:
190 divided by 234 is 0 with a remainder of 190.
The next digit of our result is 0. 
Result so far: 3880.0
Subtracting 0 from 190 leaves us with 190.
Fetch the next digit (7) from the dividend, attach it to 190 and continue: 1907 / 234

Advancing to step 7:
The number 234 fits into 1907 8 times, leaving a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 38808.0
Subtracting 1872 from 1907 leaves us with 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 234

Step 8:
353 divided by 234 is 1 with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 388081.0
Subtracting 234 from 353 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 9:
234 goes into 1190 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 388081.5
If we subtract 1170 from 1190, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
If we divide 200 by 234, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 388081.5
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
2000 divided by 234 is 8 with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 388081.508
If we subtract 1872 from 2000, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 12:
When dividing 1280 by 234, we get 5 with a remainder of 110.
The next digit of our result is 5. 
Result so far: 388081.5085
Subtracting 1170 from 1280 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 13:
If we divide 1100 by 234, we get 4 and a remainder of 164.
Use 4 as the next digit of our solution. 
Result so far: 388081.50854
Subtracting 936 from 1100 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 14:
1640 divided by 234 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 388081.508547
Subtracting 1638 from 1640 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 15:
If we divide 20 by 234, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 388081.508547
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
If we divide 200 by 234, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 388081.508547
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 388081.508547 with a remaining 2e-07.
