Let's divide 70854491 by 345
The aim is to understand the frequency of 345 in 70854491.

Going ahead to step 1:
The number 345 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 345

Advancing to step 2:
345 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 345

On to step 3:
When dividing 708 by 345, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 690 from 708 to get 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 345

Let's proceed to step 4:
The number 345 fits into 185 0 times, leaving a remainder of 185.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 185, we end up with 185.
Grab the next digit (4) from the dividend, add it to 185, then carry on: 1854 / 345

Moving on to step 5:
When dividing 1854 by 345, we get 5 with a remainder of 129.
Put 5 as the next digit of the answer. 
Result so far: 205.0
If we subtract 1725 from 1854, we get 129.
Bring next digit (4) of the dividend behind the 129 and repeat the process: 1294 / 345

Step 6:
The number 345 fits into 1294 3 times, leaving a remainder of 259.
Use 3 as the next digit of our solution. 
Result so far: 2053.0
If we subtract 1035 from 1294, we get 259.
Bring next digit (9) of the dividend behind the 259 and repeat the process: 2599 / 345

On to step 7:
When dividing 2599 by 345, we get 7 with a remainder of 184.
The next digit of our result is 7. 
Result so far: 20537.0
Subtracting 2415 from 2599 leaves us with 184.
Take the next digit (1) from the dividend and append it to 184, then repeat: 1841 / 345

Moving on to step 8:
When dividing 1841 by 345, we get 5 with a remainder of 116.
The next digit of our result is 5. 
Result so far: 205375.0
Deduct 1725 from 1841 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
If we divide 1160 by 345, we get 3 and a remainder of 125.
Record the quotient 3 as the next digit in the result. 
Result so far: 205375.3
Deduct 1035 from 1160 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 10:
1250 divided by 345 is 3 with a remainder of 215.
The number 3 becomes the next digit in our result. 
Result so far: 205375.33
Subtract 1035 from 1250 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Our division results in 205375.33 with a remaining 0.215.
