We look at the division of 8539670 by 612 
The aim is to understand the frequency of 612 in 8539670.

Advancing to step 1:
612 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 612

Moving on to step 2:
If we divide 85 by 612, we get 0 and a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Include the next digit (3) from the dividend after 85, then repeat: 853 / 612

Moving on to step 3:
612 goes into 853 1 times with a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 241 after subtracting 612 from 853.
Append the next digit (9) from the dividend to 241 and continue with: 2419 / 612

Advancing to step 4:
612 goes into 2419 3 times with a remainder of 583.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 583 after subtracting 1836 from 2419.
Grab the next digit (6) from the dividend, add it to 583, then carry on: 5836 / 612

Going ahead to step 5:
612 can be fit into 5836 9 times, resulting in a remainder of 328.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Deduct 5508 from 5836 and we're left with 328.
Include the next digit (7) from the dividend after 328, then repeat: 3287 / 612

Advancing to step 6:
612 can be fit into 3287 5 times, resulting in a remainder of 227.
Put 5 as the next digit of the answer. 
Result so far: 1395.0
Subtract 3060 from 3287 to get 227.
Append the next digit (0) from the dividend to 227 and continue with: 2270 / 612

Moving on to step 7:
When dividing 2270 by 612, we get 3 with a remainder of 434.
Record the quotient 3 as the next digit in the result. 
Result so far: 13953.0
The remainder is 434 after subtracting 1836 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 8:
612 can be fit into 4340 7 times, resulting in a remainder of 56.
The next digit of our result is 7. 
Result so far: 13953.7
If we subtract 4284 from 4340, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
612 can be fit into 560 0 times, resulting in a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 13953.7
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 10:
The number 612 fits into 5600 9 times, leaving a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 13953.709
If we take 5508 away from 5600, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 11:
The number 612 fits into 920 1 times, leaving a remainder of 308.
Put 1 as the next digit of the answer. 
Result so far: 13953.7091
If we subtract 612 from 920, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 12:
612 can be fit into 3080 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 13953.70915
If we take 3060 away from 3080, we end up 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.

Advancing to step 13:
612 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 13953.70915
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
612 goes into 2000 3 times with a remainder of 164.
Use 3 as the next digit of our solution. 
Result so far: 13953.7091503
Subtracting 1836 from 2000 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 15:
The number 612 fits into 1640 2 times, leaving a remainder of 416.
Put 2 as the next digit of the answer. 
Result so far: 13953.70915032
If we subtract 1224 from 1640, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The quotient of the division is 13953.70915032, and the remainder is 4.16e-07.
