We're dividing 70554378 by 147 
The aim is to understand the frequency of 147 in 70554378.

Advancing to step 1:
147 can be fit into 7 0 times, resulting in 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.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 147

Moving on to step 2:
70 divided by 147 is 0 with 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 (5) from the dividend, attach it to 70 and continue: 705 / 147

Going ahead to step 3:
705 divided by 147 is 4 with a remainder of 117.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 117 after subtracting 588 from 705.
Bring next digit (5) of the dividend behind the 117 and repeat the process: 1175 / 147

Going ahead to step 4:
147 goes into 1175 7 times with a remainder of 146.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 1029 from 1175 leaves us with 146.
Grab the next digit (4) from the dividend, add it to 146, then carry on: 1464 / 147

Going ahead to step 5:
If we divide 1464 by 147, we get 9 and a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 479.0
If we take 1323 away from 1464, we end up with 141.
Take the next digit (3) from the dividend and append it to 141, then repeat: 1413 / 147

On to step 6:
When dividing 1413 by 147, we get 9 with a remainder of 90.
The next digit of our result is 9. 
Result so far: 4799.0
The remainder is 90 after subtracting 1323 from 1413.
Grab the next digit (7) from the dividend, add it to 90, then carry on: 907 / 147

Going ahead to step 7:
147 goes into 907 6 times with a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 47996.0
Subtract 882 from 907 to get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 147

Going ahead to step 8:
147 goes into 258 1 times with a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 479961.0
If we take 147 away from 258, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 9:
147 can be fit into 1110 7 times, resulting in a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 479961.7
Subtract 1029 from 1110 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 10:
When dividing 810 by 147, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 479961.75
Deduct 735 from 810 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
If we divide 750 by 147, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 479961.755
If we take 735 away from 750, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 479961.755 with a remainder of 0.0015.
