Let's divide 70180026 by 354
The aim is to understand the frequency of 354 in 70180026.

Step 1:
When dividing 7 by 354, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 354

Moving on to step 2:
If we divide 70 by 354, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 354

Going ahead to step 3:
The number 354 fits into 701 1 times, leaving a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 354 from 701 to get 347.
Append the next digit (8) from the dividend to 347 and continue with: 3478 / 354

Going ahead to step 4:
3478 divided by 354 is 9 with a remainder of 292.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 3186 from 3478 and we're left with 292.
Bring next digit (0) of the dividend behind the 292 and repeat the process: 2920 / 354

Step 5:
354 goes into 2920 8 times with a remainder of 88.
The next digit of our result is 8. 
Result so far: 198.0
Subtracting 2832 from 2920 leaves us with 88.
Take the next digit (0) from the dividend and append it to 88, then repeat: 880 / 354

Moving on to step 6:
If we divide 880 by 354, we get 2 and a remainder of 172.
The number 2 becomes the next digit in our result. 
Result so far: 1982.0
The remainder is 172 after subtracting 708 from 880.
Include the next digit (2) from the dividend after 172, then repeat: 1722 / 354

Step 7:
When dividing 1722 by 354, we get 4 with a remainder of 306.
Write down 4 as next digit of the result. 
Result so far: 19824.0
If we take 1416 away from 1722, we end up with 306.
Take the next digit (6) from the dividend and append it to 306, then repeat: 3066 / 354

Advancing to step 8:
If we divide 3066 by 354, we get 8 and a remainder of 234.
Put 8 as the next digit of the answer. 
Result so far: 198248.0
If we subtract 2832 from 3066, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 9:
354 goes into 2340 6 times with a remainder of 216.
Write down 6 as next digit of the result. 
Result so far: 198248.6
If we subtract 2124 from 2340, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 10:
354 can be fit into 2160 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 198248.66
If we take 2124 away from 2160, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 198248.66 and a remainder of 0.036.
