48999991 divided by 234 
The aim is to understand the frequency of 234 in 48999991.

Step 1:
234 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 234

Let's proceed to step 2:
The number 234 fits into 48 0 times, leaving a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 234

Let's proceed to step 3:
489 divided by 234 is 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 468 from 489 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 234

Step 4:
When dividing 219 by 234, we get 0 with a remainder of 219.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 219, we end up with 219.
Include the next digit (9) from the dividend after 219, then repeat: 2199 / 234

Let's proceed to step 5:
234 can be fit into 2199 9 times, resulting in a remainder of 93.
The next digit of our result is 9. 
Result so far: 209.0
The remainder is 93 after subtracting 2106 from 2199.
Include the next digit (9) from the dividend after 93, then repeat: 939 / 234

Step 6:
The number 234 fits into 939 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 2094.0
Subtracting 936 from 939 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 234

On to step 7:
If we divide 39 by 234, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 20940.0
If we subtract 0 from 39, we get 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 234

Moving on to step 8:
The number 234 fits into 391 1 times, leaving a remainder of 157.
Record the quotient 1 as the next digit in the result. 
Result so far: 209401.0
If we subtract 234 from 391, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 9:
The number 234 fits into 1570 6 times, leaving a remainder of 166.
Use 6 as the next digit of our solution. 
Result so far: 209401.6
Subtracting 1404 from 1570 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 10:
If we divide 1660 by 234, we get 7 and a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 209401.67
If we take 1638 away from 1660, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
220 divided by 234 is 0 with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 209401.67
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
When dividing 2200 by 234, we get 9 with a remainder of 94.
Use 9 as the next digit of our solution. 
Result so far: 209401.6709
Subtract 2106 from 2200 to 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.

Moving on to step 13:
When dividing 940 by 234, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 209401.67094
Subtracting 936 from 940 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
40 divided by 234 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 209401.67094
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
400 divided by 234 is 1 with a remainder of 166.
Record the quotient 1 as the next digit in the result. 
Result so far: 209401.6709401
Subtract 234 from 400 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 16:
234 can be fit into 1660 7 times, resulting in a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 209401.67094017
If we subtract 1638 from 1660, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 209401.67094017 and a remainder of 2.2e-08.
