10345457 ÷ 198 
The aim is to understand the frequency of 198 in 10345457.

On to step 1:
The number 198 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 198

Let's proceed to step 2:
When dividing 10 by 198, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 198

Moving on to step 3:
When dividing 103 by 198, we get 0 with a remainder of 103.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 103 to get 103.
Grab the next digit (4) from the dividend, add it to 103, then carry on: 1034 / 198

Moving on to step 4:
1034 divided by 198 is 5 with a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 990 from 1034, we get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 198

Let's proceed to step 5:
198 goes into 445 2 times with a remainder of 49.
The next digit of our result is 2. 
Result so far: 52.0
If we subtract 396 from 445, we get 49.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 198

Step 6:
198 can be fit into 494 2 times, resulting in a remainder of 98.
The next digit of our result is 2. 
Result so far: 522.0
Deduct 396 from 494 and we're left with 98.
Fetch the next digit (5) from the dividend, attach it to 98 and continue: 985 / 198

Moving on to step 7:
When dividing 985 by 198, we get 4 with a remainder of 193.
The next digit of our result is 4. 
Result so far: 5224.0
Subtracting 792 from 985 leaves us with 193.
Bring next digit (7) of the dividend behind the 193 and repeat the process: 1937 / 198

Step 8:
198 goes into 1937 9 times with a remainder of 155.
The next digit of our result is 9. 
Result so far: 52249.0
Deduct 1782 from 1937 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
198 goes into 1550 7 times with a remainder of 164.
The number 7 becomes the next digit in our result. 
Result so far: 52249.7
Subtracting 1386 from 1550 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.

Advancing to step 10:
The number 198 fits into 1640 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 52249.78
If we take 1584 away from 1640, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
198 can be fit into 560 2 times, resulting in a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 52249.782
If we take 396 away from 560, we end up 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.

Moving on to step 12:
198 can be fit into 1640 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 52249.7828
The remainder is 56 after subtracting 1584 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
The number 198 fits into 560 2 times, leaving a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 52249.78282
Subtract 396 from 560 to get 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:
198 can be fit into 1640 8 times, resulting in a remainder of 56.
The next digit of our result is 8. 
Result so far: 52249.782828
If we subtract 1584 from 1640, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 15:
560 divided by 198 is 2 with a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 52249.7828282
Deduct 396 from 560 and we're left 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.

Let's proceed to step 16:
198 can be fit into 1640 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 52249.78282828
Subtracting 1584 from 1640 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 52249.78282828 and a remainder of 5.6e-08.
