We're dividing 99598142 by 846 
The aim is to understand the frequency of 846 in 99598142.

On to step 1:
When dividing 9 by 846, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 846

On to step 2:
If we divide 99 by 846, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (5) from the dividend, add it to 99, then carry on: 995 / 846

Moving on to step 3:
When dividing 995 by 846, we get 1 with a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 846 from 995 and we're left with 149.
Append the next digit (9) from the dividend to 149 and continue with: 1499 / 846

Advancing to step 4:
The number 846 fits into 1499 1 times, leaving a remainder of 653.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 846 away from 1499, we end up with 653.
Bring next digit (8) of the dividend behind the 653 and repeat the process: 6538 / 846

Let's proceed to step 5:
If we divide 6538 by 846, we get 7 and a remainder of 616.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we subtract 5922 from 6538, we get 616.
Fetch the next digit (1) from the dividend, attach it to 616 and continue: 6161 / 846

Moving on to step 6:
If we divide 6161 by 846, we get 7 and a remainder of 239.
The number 7 becomes the next digit in our result. 
Result so far: 1177.0
If we take 5922 away from 6161, we end up with 239.
Fetch the next digit (4) from the dividend, attach it to 239 and continue: 2394 / 846

Advancing to step 7:
When dividing 2394 by 846, we get 2 with a remainder of 702.
Record the quotient 2 as the next digit in the result. 
Result so far: 11772.0
Deduct 1692 from 2394 and we're left with 702.
Include the next digit (2) from the dividend after 702, then repeat: 7022 / 846

Step 8:
7022 divided by 846 is 8 with a remainder of 254.
The next digit of our result is 8. 
Result so far: 117728.0
Subtracting 6768 from 7022 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 9:
The number 846 fits into 2540 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 117728.3
If we take 2538 away from 2540, we end up 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.

Going ahead to step 10:
846 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 117728.3
Subtract 0 from 20 to 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 11:
846 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 117728.3
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.

After the division, we end up with 117728.3 and a remainder of 0.02.
