We look at the division of 52152213 by 354 
The aim is to understand the frequency of 354 in 52152213.

Moving on to step 1:
354 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 354

Going ahead to step 2:
When dividing 52 by 354, we get 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 354

Going ahead to step 3:
When dividing 521 by 354, we get 1 with a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 354 from 521 to get 167.
Bring next digit (5) of the dividend behind the 167 and repeat the process: 1675 / 354

Advancing to step 4:
354 can be fit into 1675 4 times, resulting in a remainder of 259.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 1416 from 1675, we get 259.
Include the next digit (2) from the dividend after 259, then repeat: 2592 / 354

Let's proceed to step 5:
If we divide 2592 by 354, we get 7 and a remainder of 114.
Put 7 as the next digit of the answer. 
Result so far: 147.0
If we subtract 2478 from 2592, we get 114.
Bring next digit (2) of the dividend behind the 114 and repeat the process: 1142 / 354

On to step 6:
354 goes into 1142 3 times with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 1473.0
The remainder is 80 after subtracting 1062 from 1142.
Take the next digit (1) from the dividend and append it to 80, then repeat: 801 / 354

Moving on to step 7:
354 goes into 801 2 times with a remainder of 93.
The next digit of our result is 2. 
Result so far: 14732.0
If we take 708 away from 801, we end up with 93.
Fetch the next digit (3) from the dividend, attach it to 93 and continue: 933 / 354

Going ahead to step 8:
If we divide 933 by 354, we get 2 and a remainder of 225.
Use 2 as the next digit of our solution. 
Result so far: 147322.0
If we subtract 708 from 933, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 9:
When dividing 2250 by 354, we get 6 with a remainder of 126.
Record the quotient 6 as the next digit in the result. 
Result so far: 147322.6
Subtract 2124 from 2250 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 10:
354 can be fit into 1260 3 times, resulting in a remainder of 198.
Put 3 as the next digit of the answer. 
Result so far: 147322.63
If we subtract 1062 from 1260, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 11:
The number 354 fits into 1980 5 times, leaving a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 147322.635
Deduct 1770 from 1980 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
2100 divided by 354 is 5 with a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 147322.6355
Subtract 1770 from 2100 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

After the division, we end up with 147322.6355 and a remainder of 0.0033.
