We're dividing 351608 by 93 
The aim is to understand the frequency of 93 in 351608.

On to step 1:
93 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 93

Step 2:
35 divided by 93 is 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 93

Advancing to step 3:
93 goes into 351 3 times with a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 279 from 351 and we're left with 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 93

Advancing to step 4:
726 divided by 93 is 7 with a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 651 from 726, we get 75.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 93

Step 5:
If we divide 750 by 93, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 378.0
Subtract 744 from 750 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 93

Moving on to step 6:
68 divided by 93 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 3780.0
Subtracting 0 from 68 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
93 goes into 680 7 times with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 3780.7
Subtracting 651 from 680 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
290 divided by 93 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3780.73
If we subtract 279 from 290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
110 divided by 93 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 3780.731
Deduct 93 from 110 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
If we divide 170 by 93, we get 1 and a remainder of 77.
The next digit of our result is 1. 
Result so far: 3780.7311
If we subtract 93 from 170, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Our division results in 3780.7311 with a remaining 0.00077.
