We look at the division of 61938072 by 666 
The aim is to understand the frequency of 666 in 61938072.

Moving on to step 1:
The number 666 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 666

Let's proceed to step 2:
666 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 666

Advancing to step 3:
666 can be fit into 619 0 times, resulting in a remainder of 619.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 619 leaves us with 619.
Grab the next digit (3) from the dividend, add it to 619, then carry on: 6193 / 666

Step 4:
If we divide 6193 by 666, we get 9 and a remainder of 199.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 5994 from 6193 to get 199.
Bring next digit (8) of the dividend behind the 199 and repeat the process: 1998 / 666

Advancing to step 5:
If we divide 1998 by 666, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Deduct 1998 from 1998 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 666

Let's proceed to step 6:
666 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 930.0
If we subtract 0 from 0, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 666

Advancing to step 7:
666 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 9300.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 666

Let's proceed to step 8:
72 divided by 666 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 93000.0
Subtract 0 from 72 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
When dividing 720 by 666, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 93000.1
Deduct 666 from 720 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
When dividing 540 by 666, we get 0 with a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 93000.1
The remainder is 540 after subtracting 0 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 11:
666 goes into 5400 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 93000.108
The remainder is 72 after subtracting 5328 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
If we divide 720 by 666, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 93000.1081
Subtracting 666 from 720 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
If we divide 540 by 666, we get 0 and a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 93000.1081
Subtracting 0 from 540 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 14:
666 can be fit into 5400 8 times, resulting in a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 93000.108108
Deduct 5328 from 5400 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 15:
666 can be fit into 720 1 times, resulting in a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 93000.1081081
Subtract 666 from 720 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 16:
The number 666 fits into 540 0 times, leaving a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 93000.1081081
Deduct 0 from 540 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

In conclusion, the division gives 93000.1081081 with a balance of 5.4e-07.
