We look at the division of 73907117 by 669 
The aim is to understand the frequency of 669 in 73907117.

Moving on to step 1:
When dividing 7 by 669, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 669

Going ahead to step 2:
669 goes into 73 0 times with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 669

On to step 3:
The number 669 fits into 739 1 times, leaving a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 669 from 739 leaves us with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 669

Advancing to step 4:
700 divided by 669 is 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 669 from 700, we get 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 669

On to step 5:
669 goes into 317 0 times with a remainder of 317.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtracting 0 from 317 leaves us with 317.
Include the next digit (1) from the dividend after 317, then repeat: 3171 / 669

Moving on to step 6:
The number 669 fits into 3171 4 times, leaving a remainder of 495.
Record the quotient 4 as the next digit in the result. 
Result so far: 1104.0
Subtract 2676 from 3171 to get 495.
Fetch the next digit (1) from the dividend, attach it to 495 and continue: 4951 / 669

Advancing to step 7:
4951 divided by 669 is 7 with a remainder of 268.
Record the quotient 7 as the next digit in the result. 
Result so far: 11047.0
Subtracting 4683 from 4951 leaves us with 268.
Take the next digit (7) from the dividend and append it to 268, then repeat: 2687 / 669

Going ahead to step 8:
If we divide 2687 by 669, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 110474.0
Subtracting 2676 from 2687 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
If we divide 110 by 669, we get 0 and a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 110474.0
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
When dividing 1100 by 669, we get 1 with a remainder of 431.
Put 1 as the next digit of the answer. 
Result so far: 110474.01
If we take 669 away from 1100, we end up with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Advancing to step 11:
669 goes into 4310 6 times with a remainder of 296.
Use 6 as the next digit of our solution. 
Result so far: 110474.016
Deduct 4014 from 4310 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 12:
669 can be fit into 2960 4 times, resulting in a remainder of 284.
The number 4 becomes the next digit in our result. 
Result so far: 110474.0164
If we take 2676 away from 2960, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 13:
When dividing 2840 by 669, we get 4 with a remainder of 164.
The number 4 becomes the next digit in our result. 
Result so far: 110474.01644
The remainder is 164 after subtracting 2676 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

In conclusion, the division gives 110474.01644 with a balance of 0.000164.
