93349359 ÷ 816 
The aim is to understand the frequency of 816 in 93349359.

Let's proceed to step 1:
If we divide 9 by 816, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 816

On to step 2:
When dividing 93 by 816, we get 0 with a remainder of 93.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 93 leaves us with 93.
Include the next digit (3) from the dividend after 93, then repeat: 933 / 816

On to step 3:
If we divide 933 by 816, we get 1 and a remainder of 117.
The next digit of our result is 1. 
Result so far: 1.0
If we take 816 away from 933, we end up with 117.
Grab the next digit (4) from the dividend, add it to 117, then carry on: 1174 / 816

Moving on to step 4:
When dividing 1174 by 816, we get 1 with a remainder of 358.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 816 from 1174 to get 358.
Append the next digit (9) from the dividend to 358 and continue with: 3589 / 816

Going ahead to step 5:
When dividing 3589 by 816, we get 4 with a remainder of 325.
Write down 4 as next digit of the result. 
Result so far: 114.0
Subtracting 3264 from 3589 leaves us with 325.
Grab the next digit (3) from the dividend, add it to 325, then carry on: 3253 / 816

Going ahead to step 6:
816 goes into 3253 3 times with a remainder of 805.
Record the quotient 3 as the next digit in the result. 
Result so far: 1143.0
Deduct 2448 from 3253 and we're left with 805.
Include the next digit (5) from the dividend after 805, then repeat: 8055 / 816

Going ahead to step 7:
8055 divided by 816 is 9 with a remainder of 711.
The next digit of our result is 9. 
Result so far: 11439.0
The remainder is 711 after subtracting 7344 from 8055.
Bring next digit (9) of the dividend behind the 711 and repeat the process: 7119 / 816

Moving on to step 8:
7119 divided by 816 is 8 with a remainder of 591.
The number 8 becomes the next digit in our result. 
Result so far: 114398.0
Subtracting 6528 from 7119 leaves us with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Moving on to step 9:
816 goes into 5910 7 times with a remainder of 198.
The next digit of our result is 7. 
Result so far: 114398.7
Deduct 5712 from 5910 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 10:
When dividing 1980 by 816, we get 2 with a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 114398.72
If we subtract 1632 from 1980, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 11:
816 can be fit into 3480 4 times, resulting in a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 114398.724
The remainder is 216 after subtracting 3264 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 12:
The number 816 fits into 2160 2 times, leaving a remainder of 528.
Put 2 as the next digit of the answer. 
Result so far: 114398.7242
Subtracting 1632 from 2160 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 13:
816 can be fit into 5280 6 times, resulting in a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 114398.72426
Subtracting 4896 from 5280 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 14:
If we divide 3840 by 816, we get 4 and a remainder of 576.
Put 4 as the next digit of the answer. 
Result so far: 114398.724264
Subtracting 3264 from 3840 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 15:
If we divide 5760 by 816, we get 7 and a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 114398.7242647
Deduct 5712 from 5760 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
816 can be fit into 480 0 times, resulting in a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 114398.7242647
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final result is 114398.7242647 with a remainder of 4.8e-07.
