91726631 divided by 666 
The aim is to understand the frequency of 666 in 91726631.

Going ahead to step 1:
If we divide 9 by 666, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 666

Step 2:
If we divide 91 by 666, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Grab the next digit (7) from the dividend, add it to 91, then carry on: 917 / 666

Advancing to step 3:
When dividing 917 by 666, we get 1 with a remainder of 251.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 251 after subtracting 666 from 917.
Bring next digit (2) of the dividend behind the 251 and repeat the process: 2512 / 666

Let's proceed to step 4:
666 goes into 2512 3 times with a remainder of 514.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1998 from 2512, we get 514.
Take the next digit (6) from the dividend and append it to 514, then repeat: 5146 / 666

Going ahead to step 5:
When dividing 5146 by 666, we get 7 with a remainder of 484.
Write down 7 as next digit of the result. 
Result so far: 137.0
The remainder is 484 after subtracting 4662 from 5146.
Fetch the next digit (6) from the dividend, attach it to 484 and continue: 4846 / 666

Going ahead to step 6:
The number 666 fits into 4846 7 times, leaving a remainder of 184.
Write down 7 as next digit of the result. 
Result so far: 1377.0
The remainder is 184 after subtracting 4662 from 4846.
Bring next digit (3) of the dividend behind the 184 and repeat the process: 1843 / 666

On to step 7:
When dividing 1843 by 666, we get 2 with a remainder of 511.
Record the quotient 2 as the next digit in the result. 
Result so far: 13772.0
If we take 1332 away from 1843, we end up with 511.
Bring next digit (1) of the dividend behind the 511 and repeat the process: 5111 / 666

Advancing to step 8:
5111 divided by 666 is 7 with a remainder of 449.
The next digit of our result is 7. 
Result so far: 137727.0
If we subtract 4662 from 5111, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 9:
If we divide 4490 by 666, we get 6 and a remainder of 494.
Write down 6 as next digit of the result. 
Result so far: 137727.6
If we subtract 3996 from 4490, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 10:
4940 divided by 666 is 7 with a remainder of 278.
Put 7 as the next digit of the answer. 
Result so far: 137727.67
Subtracting 4662 from 4940 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 11:
The number 666 fits into 2780 4 times, leaving a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 137727.674
Subtracting 2664 from 2780 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 12:
1160 divided by 666 is 1 with a remainder of 494.
The number 1 becomes the next digit in our result. 
Result so far: 137727.6741
Subtracting 666 from 1160 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 13:
The number 666 fits into 4940 7 times, leaving a remainder of 278.
The next digit of our result is 7. 
Result so far: 137727.67417
If we take 4662 away from 4940, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 14:
The number 666 fits into 2780 4 times, leaving a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 137727.674174
If we subtract 2664 from 2780, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 15:
666 goes into 1160 1 times with a remainder of 494.
The next digit of our result is 1. 
Result so far: 137727.6741741
If we take 666 away from 1160, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 16:
If we divide 4940 by 666, we get 7 and a remainder of 278.
Use 7 as the next digit of our solution. 
Result so far: 137727.67417417
Subtracting 4662 from 4940 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The quotient of the division is 137727.67417417, and the remainder is 2.78e-07.
