67990153 ÷ 667 
The aim is to understand the frequency of 667 in 67990153.

On to step 1:
667 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 667

Moving on to step 2:
When dividing 67 by 667, we get 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 667

Advancing to step 3:
679 divided by 667 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 667 from 679 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 667

Step 4:
667 goes into 129 0 times with a remainder of 129.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 129 to get 129.
Fetch the next digit (0) from the dividend, attach it to 129 and continue: 1290 / 667

Let's proceed to step 5:
667 can be fit into 1290 1 times, resulting in a remainder of 623.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we subtract 667 from 1290, we get 623.
Append the next digit (1) from the dividend to 623 and continue with: 6231 / 667

On to step 6:
When dividing 6231 by 667, we get 9 with a remainder of 228.
The next digit of our result is 9. 
Result so far: 1019.0
The remainder is 228 after subtracting 6003 from 6231.
Fetch the next digit (5) from the dividend, attach it to 228 and continue: 2285 / 667

On to step 7:
The number 667 fits into 2285 3 times, leaving a remainder of 284.
Put 3 as the next digit of the answer. 
Result so far: 10193.0
Deduct 2001 from 2285 and we're left with 284.
Include the next digit (3) from the dividend after 284, then repeat: 2843 / 667

Let's proceed to step 8:
667 goes into 2843 4 times with a remainder of 175.
Record the quotient 4 as the next digit in the result. 
Result so far: 101934.0
Deduct 2668 from 2843 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 9:
When dividing 1750 by 667, we get 2 with a remainder of 416.
Use 2 as the next digit of our solution. 
Result so far: 101934.2
Subtracting 1334 from 1750 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 10:
667 goes into 4160 6 times with a remainder of 158.
The next digit of our result is 6. 
Result so far: 101934.26
Deduct 4002 from 4160 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 11:
667 can be fit into 1580 2 times, resulting in a remainder of 246.
The number 2 becomes the next digit in our result. 
Result so far: 101934.262
Subtracting 1334 from 1580 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 12:
667 goes into 2460 3 times with a remainder of 459.
Use 3 as the next digit of our solution. 
Result so far: 101934.2623
Deduct 2001 from 2460 and we're left with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Advancing to step 13:
If we divide 4590 by 667, we get 6 and a remainder of 588.
Record the quotient 6 as the next digit in the result. 
Result so far: 101934.26236
If we take 4002 away from 4590, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 14:
When dividing 5880 by 667, we get 8 with a remainder of 544.
Use 8 as the next digit of our solution. 
Result so far: 101934.262368
If we take 5336 away from 5880, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 15:
If we divide 5440 by 667, we get 8 and a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 101934.2623688
If we take 5336 away from 5440, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 101934.2623688 with a remainder of 1.04e-06.
