13493021 ÷ 147 
The aim is to understand the frequency of 147 in 13493021.

Advancing to step 1:
If we divide 1 by 147, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 147

Let's proceed to step 2:
When dividing 13 by 147, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 147

Advancing to step 3:
147 can be fit into 134 0 times, resulting in a remainder of 134.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 134, we get 134.
Include the next digit (9) from the dividend after 134, then repeat: 1349 / 147

Moving on to step 4:
147 goes into 1349 9 times with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 26 after subtracting 1323 from 1349.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 147

Let's proceed to step 5:
If we divide 263 by 147, we get 1 and a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we subtract 147 from 263, we get 116.
Take the next digit (0) from the dividend and append it to 116, then repeat: 1160 / 147

Going ahead to step 6:
When dividing 1160 by 147, we get 7 with a remainder of 131.
Put 7 as the next digit of the answer. 
Result so far: 917.0
Subtract 1029 from 1160 to get 131.
Include the next digit (2) from the dividend after 131, then repeat: 1312 / 147

Let's proceed to step 7:
The number 147 fits into 1312 8 times, leaving a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 9178.0
If we subtract 1176 from 1312, we get 136.
Fetch the next digit (1) from the dividend, attach it to 136 and continue: 1361 / 147

Moving on to step 8:
1361 divided by 147 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 91789.0
If we take 1323 away from 1361, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
If we divide 380 by 147, we get 2 and a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 91789.2
Subtract 294 from 380 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 10:
860 divided by 147 is 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 91789.25
Deduct 735 from 860 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 11:
147 goes into 1250 8 times with a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 91789.258
Subtract 1176 from 1250 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
740 divided by 147 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 91789.2585
Subtract 735 from 740 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
When dividing 50 by 147, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 91789.2585
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
If we divide 500 by 147, we get 3 and a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 91789.258503
Subtract 441 from 500 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 15:
If we divide 590 by 147, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 91789.2585034
If we subtract 588 from 590, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 16:
When dividing 20 by 147, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 91789.2585034
Deduct 0 from 20 and we're left 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.

Our division results in 91789.2585034 with a remaining 2e-08.
