We divide 66907988 by 667
The aim is to understand the frequency of 667 in 66907988.

Moving on to step 1:
The number 667 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 667

On to step 2:
The number 667 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 667

Advancing to step 3:
When dividing 669 by 667, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 667 from 669 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 667

On to step 4:
667 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 20 to get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 667

Moving on to step 5:
667 can be fit into 207 0 times, resulting in a remainder of 207.
The next digit of our result is 0. 
Result so far: 100.0
If we subtract 0 from 207, we get 207.
Take the next digit (9) from the dividend and append it to 207, then repeat: 2079 / 667

Let's proceed to step 6:
The number 667 fits into 2079 3 times, leaving a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 1003.0
Subtract 2001 from 2079 to get 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 667

Let's proceed to step 7:
The number 667 fits into 788 1 times, leaving a remainder of 121.
The number 1 becomes the next digit in our result. 
Result so far: 10031.0
If we subtract 667 from 788, we get 121.
Fetch the next digit (8) from the dividend, attach it to 121 and continue: 1218 / 667

Advancing to step 8:
The number 667 fits into 1218 1 times, leaving a remainder of 551.
Put 1 as the next digit of the answer. 
Result so far: 100311.0
The remainder is 551 after subtracting 667 from 1218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

On to step 9:
If we divide 5510 by 667, we get 8 and a remainder of 174.
Use 8 as the next digit of our solution. 
Result so far: 100311.8
If we take 5336 away from 5510, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 10:
1740 divided by 667 is 2 with a remainder of 406.
The number 2 becomes the next digit in our result. 
Result so far: 100311.82
If we take 1334 away from 1740, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 11:
If we divide 4060 by 667, we get 6 and a remainder of 58.
The next digit of our result is 6. 
Result so far: 100311.826
Subtract 4002 from 4060 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
667 can be fit into 580 0 times, resulting in a remainder of 580.
Record the quotient 0 as the next digit in the result. 
Result so far: 100311.826
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 13:
667 can be fit into 5800 8 times, resulting in a remainder of 464.
The number 8 becomes the next digit in our result. 
Result so far: 100311.82608
The remainder is 464 after subtracting 5336 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 14:
When dividing 4640 by 667, we get 6 with a remainder of 638.
The next digit of our result is 6. 
Result so far: 100311.826086
If we subtract 4002 from 4640, we get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 15:
667 can be fit into 6380 9 times, resulting in a remainder of 377.
Put 9 as the next digit of the answer. 
Result so far: 100311.8260869
Subtracting 6003 from 6380 leaves us 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.

Advancing to step 16:
The number 667 fits into 3770 5 times, leaving a remainder of 435.
Record the quotient 5 as the next digit in the result. 
Result so far: 100311.82608695
The remainder is 435 after subtracting 3335 from 3770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

The final outcome is 100311.82608695, with a leftover of 4.35e-07.
