We look at the division of 99388074 by 802 
The aim is to understand the frequency of 802 in 99388074.

Going ahead to step 1:
802 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 802

Advancing to step 2:
If we divide 99 by 802, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 802

Step 3:
When dividing 993 by 802, we get 1 with a remainder of 191.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 802 from 993 to get 191.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 802

Going ahead to step 4:
802 goes into 1918 2 times with a remainder of 314.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1604 away from 1918, we end up with 314.
Include the next digit (8) from the dividend after 314, then repeat: 3148 / 802

Going ahead to step 5:
802 goes into 3148 3 times with a remainder of 742.
Put 3 as the next digit of the answer. 
Result so far: 123.0
The remainder is 742 after subtracting 2406 from 3148.
Append the next digit (0) from the dividend to 742 and continue with: 7420 / 802

Step 6:
When dividing 7420 by 802, we get 9 with a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 1239.0
Deduct 7218 from 7420 and we're left with 202.
Grab the next digit (7) from the dividend, add it to 202, then carry on: 2027 / 802

On to step 7:
802 goes into 2027 2 times with a remainder of 423.
The next digit of our result is 2. 
Result so far: 12392.0
The remainder is 423 after subtracting 1604 from 2027.
Fetch the next digit (4) from the dividend, attach it to 423 and continue: 4234 / 802

Going ahead to step 8:
802 goes into 4234 5 times with a remainder of 224.
The next digit of our result is 5. 
Result so far: 123925.0
If we take 4010 away from 4234, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 9:
802 goes into 2240 2 times with a remainder of 636.
Put 2 as the next digit of the answer. 
Result so far: 123925.2
Deduct 1604 from 2240 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 10:
The number 802 fits into 6360 7 times, leaving a remainder of 746.
Write down 7 as next digit of the result. 
Result so far: 123925.27
The remainder is 746 after subtracting 5614 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Moving on to step 11:
When dividing 7460 by 802, we get 9 with a remainder of 242.
The next digit of our result is 9. 
Result so far: 123925.279
Subtracting 7218 from 7460 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 12:
802 can be fit into 2420 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 123925.2793
Deduct 2406 from 2420 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
If we divide 140 by 802, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 123925.2793
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
If we divide 1400 by 802, we get 1 and a remainder of 598.
The number 1 becomes the next digit in our result. 
Result so far: 123925.279301
The remainder is 598 after subtracting 802 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

On to step 15:
The number 802 fits into 5980 7 times, leaving a remainder of 366.
Use 7 as the next digit of our solution. 
Result so far: 123925.2793017
Subtract 5614 from 5980 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 16:
802 can be fit into 3660 4 times, resulting in a remainder of 452.
Put 4 as the next digit of the answer. 
Result so far: 123925.27930174
Subtracting 3208 from 3660 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final outcome is 123925.27930174, with a leftover of 4.52e-07.
