72782531 divided by 354 
The aim is to understand the frequency of 354 in 72782531.

Going ahead to step 1:
354 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 354

Step 2:
72 divided by 354 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (7) from the dividend, add it to 72, then carry on: 727 / 354

Let's proceed to step 3:
If we divide 727 by 354, we get 2 and a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 708 away from 727, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 354

Going ahead to step 4:
354 goes into 198 0 times with a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 198 to get 198.
Append the next digit (2) from the dividend to 198 and continue with: 1982 / 354

Going ahead to step 5:
1982 divided by 354 is 5 with a remainder of 212.
Record the quotient 5 as the next digit in the result. 
Result so far: 205.0
Deduct 1770 from 1982 and we're left with 212.
Bring next digit (5) of the dividend behind the 212 and repeat the process: 2125 / 354

Moving on to step 6:
354 goes into 2125 6 times with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 2056.0
Subtract 2124 from 2125 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 354

Advancing to step 7:
354 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 20560.0
Subtract 0 from 13 to get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 354

Going ahead to step 8:
When dividing 131 by 354, we get 0 with a remainder of 131.
The next digit of our result is 0. 
Result so far: 205600.0
Subtracting 0 from 131 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
If we divide 1310 by 354, we get 3 and a remainder of 248.
The number 3 becomes the next digit in our result. 
Result so far: 205600.3
If we take 1062 away from 1310, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 10:
When dividing 2480 by 354, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 205600.37
If we take 2478 away from 2480, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
354 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 205600.37
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
354 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 205600.37
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 205600.37, with a leftover of 0.002.
