We look at the division of 8062378 by 661 
The aim is to understand the frequency of 661 in 8062378.

Moving on to step 1:
661 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 661

On to step 2:
When dividing 80 by 661, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (6) of the dividend behind the 80 and repeat the process: 806 / 661

Step 3:
661 can be fit into 806 1 times, resulting in a remainder of 145.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 661 from 806 and we're left with 145.
Append the next digit (2) from the dividend to 145 and continue with: 1452 / 661

On to step 4:
1452 divided by 661 is 2 with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1322 from 1452 and we're left with 130.
Take the next digit (3) from the dividend and append it to 130, then repeat: 1303 / 661

Advancing to step 5:
The number 661 fits into 1303 1 times, leaving a remainder of 642.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Subtract 661 from 1303 to get 642.
Fetch the next digit (7) from the dividend, attach it to 642 and continue: 6427 / 661

Advancing to step 6:
6427 divided by 661 is 9 with a remainder of 478.
The next digit of our result is 9. 
Result so far: 1219.0
The remainder is 478 after subtracting 5949 from 6427.
Include the next digit (8) from the dividend after 478, then repeat: 4788 / 661

Going ahead to step 7:
When dividing 4788 by 661, we get 7 with a remainder of 161.
Record the quotient 7 as the next digit in the result. 
Result so far: 12197.0
Subtract 4627 from 4788 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 8:
The number 661 fits into 1610 2 times, leaving a remainder of 288.
Use 2 as the next digit of our solution. 
Result so far: 12197.2
Subtract 1322 from 1610 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 9:
661 can be fit into 2880 4 times, resulting in a remainder of 236.
The next digit of our result is 4. 
Result so far: 12197.24
Subtracting 2644 from 2880 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 10:
661 goes into 2360 3 times with a remainder of 377.
Record the quotient 3 as the next digit in the result. 
Result so far: 12197.243
If we take 1983 away from 2360, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 11:
661 goes into 3770 5 times with a remainder of 465.
Put 5 as the next digit of the answer. 
Result so far: 12197.2435
If we subtract 3305 from 3770, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 12:
4650 divided by 661 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 12197.24357
Subtract 4627 from 4650 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
230 divided by 661 is 0 with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 12197.24357
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 14:
When dividing 2300 by 661, we get 3 with a remainder of 317.
Write down 3 as next digit of the result. 
Result so far: 12197.2435703
The remainder is 317 after subtracting 1983 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 15:
661 goes into 3170 4 times with a remainder of 526.
Record the quotient 4 as the next digit in the result. 
Result so far: 12197.24357034
Deduct 2644 from 3170 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

The quotient of the division is 12197.24357034, and the remainder is 5.26e-07.
