We look at the division of 85221568 by 147 
The aim is to understand the frequency of 147 in 85221568.

Advancing to step 1:
The number 147 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 147

Let's proceed to step 2:
147 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Include the next digit (2) from the dividend after 85, then repeat: 852 / 147

Going ahead to step 3:
147 goes into 852 5 times with a remainder of 117.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 735 from 852 and we're left with 117.
Grab the next digit (2) from the dividend, add it to 117, then carry on: 1172 / 147

Step 4:
147 can be fit into 1172 7 times, resulting in a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we take 1029 away from 1172, we end up with 143.
Bring next digit (1) of the dividend behind the 143 and repeat the process: 1431 / 147

On to step 5:
147 can be fit into 1431 9 times, resulting in a remainder of 108.
Use 9 as the next digit of our solution. 
Result so far: 579.0
Deduct 1323 from 1431 and we're left with 108.
Bring next digit (5) of the dividend behind the 108 and repeat the process: 1085 / 147

On to step 6:
The number 147 fits into 1085 7 times, leaving a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 5797.0
If we subtract 1029 from 1085, we get 56.
Take the next digit (6) from the dividend and append it to 56, then repeat: 566 / 147

On to step 7:
If we divide 566 by 147, we get 3 and a remainder of 125.
Write down 3 as next digit of the result. 
Result so far: 57973.0
The remainder is 125 after subtracting 441 from 566.
Grab the next digit (8) from the dividend, add it to 125, then carry on: 1258 / 147

Step 8:
147 can be fit into 1258 8 times, resulting in a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 579738.0
Subtract 1176 from 1258 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
The number 147 fits into 820 5 times, leaving a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 579738.5
If we subtract 735 from 820, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 10:
If we divide 850 by 147, we get 5 and a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 579738.55
If we subtract 735 from 850, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The quotient of the division is 579738.55, and the remainder is 0.115.
