98605352 ÷ 819 
The aim is to understand the frequency of 819 in 98605352.

Let's proceed to step 1:
819 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 819

Moving on to step 2:
If we divide 98 by 819, we get 0 and a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Grab the next digit (6) from the dividend, add it to 98, then carry on: 986 / 819

Advancing to step 3:
When dividing 986 by 819, we get 1 with a remainder of 167.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 819 from 986 and we're left with 167.
Fetch the next digit (0) from the dividend, attach it to 167 and continue: 1670 / 819

Let's proceed to step 4:
819 goes into 1670 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 32 after subtracting 1638 from 1670.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 819

Moving on to step 5:
When dividing 325 by 819, we get 0 with a remainder of 325.
The next digit of our result is 0. 
Result so far: 120.0
The remainder is 325 after subtracting 0 from 325.
Include the next digit (3) from the dividend after 325, then repeat: 3253 / 819

On to step 6:
819 goes into 3253 3 times with a remainder of 796.
The number 3 becomes the next digit in our result. 
Result so far: 1203.0
Subtract 2457 from 3253 to get 796.
Fetch the next digit (5) from the dividend, attach it to 796 and continue: 7965 / 819

Moving on to step 7:
7965 divided by 819 is 9 with a remainder of 594.
The number 9 becomes the next digit in our result. 
Result so far: 12039.0
Subtract 7371 from 7965 to get 594.
Grab the next digit (2) from the dividend, add it to 594, then carry on: 5942 / 819

On to step 8:
The number 819 fits into 5942 7 times, leaving a remainder of 209.
Put 7 as the next digit of the answer. 
Result so far: 120397.0
Subtract 5733 from 5942 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 9:
When dividing 2090 by 819, we get 2 with a remainder of 452.
The next digit of our result is 2. 
Result so far: 120397.2
The remainder is 452 after subtracting 1638 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 10:
4520 divided by 819 is 5 with a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 120397.25
If we take 4095 away from 4520, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 11:
819 can be fit into 4250 5 times, resulting in a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 120397.255
Deduct 4095 from 4250 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.

After the division, we end up with 120397.255 and a remainder of 0.0155.
