We look at the division of 71660866 by 613 
The aim is to understand the frequency of 613 in 71660866.

Moving on to step 1:
613 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 613

Going ahead to step 2:
If we divide 71 by 613, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 613

On to step 3:
The number 613 fits into 716 1 times, leaving a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 613 away from 716, we end up with 103.
Take the next digit (6) from the dividend and append it to 103, then repeat: 1036 / 613

On to step 4:
1036 divided by 613 is 1 with a remainder of 423.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 613 from 1036 to get 423.
Bring next digit (0) of the dividend behind the 423 and repeat the process: 4230 / 613

Going ahead to step 5:
613 can be fit into 4230 6 times, resulting in a remainder of 552.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
If we take 3678 away from 4230, we end up with 552.
Fetch the next digit (8) from the dividend, attach it to 552 and continue: 5528 / 613

Moving on to step 6:
If we divide 5528 by 613, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1169.0
Deduct 5517 from 5528 and we're left with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 613

Going ahead to step 7:
If we divide 116 by 613, we get 0 and a remainder of 116.
Put 0 as the next digit of the answer. 
Result so far: 11690.0
Subtracting 0 from 116 leaves us with 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 613

Advancing to step 8:
If we divide 1166 by 613, we get 1 and a remainder of 553.
Put 1 as the next digit of the answer. 
Result so far: 116901.0
If we take 613 away from 1166, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 9:
5530 divided by 613 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 116901.9
Deduct 5517 from 5530 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
613 can be fit into 130 0 times, resulting in a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 116901.9
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
When dividing 1300 by 613, we get 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 116901.902
If we take 1226 away from 1300, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
613 can be fit into 740 1 times, resulting in a remainder of 127.
The next digit of our result is 1. 
Result so far: 116901.9021
If we subtract 613 from 740, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 13:
613 goes into 1270 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 116901.90212
Subtracting 1226 from 1270 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
613 can be fit into 440 0 times, resulting in a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 116901.90212
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 15:
If we divide 4400 by 613, we get 7 and a remainder of 109.
Write down 7 as next digit of the result. 
Result so far: 116901.9021207
If we subtract 4291 from 4400, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 16:
613 can be fit into 1090 1 times, resulting in a remainder of 477.
Put 1 as the next digit of the answer. 
Result so far: 116901.90212071
If we subtract 613 from 1090, we get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Our division results in 116901.90212071 with a remaining 4.77e-07.
