45831869 divided by 669 
The aim is to understand the frequency of 669 in 45831869.

Advancing to step 1:
669 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 669

Moving on to step 2:
45 divided by 669 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 669

Moving on to step 3:
669 can be fit into 458 0 times, resulting in a remainder of 458.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 458 leaves us with 458.
Fetch the next digit (3) from the dividend, attach it to 458 and continue: 4583 / 669

Advancing to step 4:
When dividing 4583 by 669, we get 6 with a remainder of 569.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 4014 from 4583 and we're left with 569.
Fetch the next digit (1) from the dividend, attach it to 569 and continue: 5691 / 669

On to step 5:
The number 669 fits into 5691 8 times, leaving a remainder of 339.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtracting 5352 from 5691 leaves us with 339.
Include the next digit (8) from the dividend after 339, then repeat: 3398 / 669

Going ahead to step 6:
If we divide 3398 by 669, we get 5 and a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 685.0
Subtracting 3345 from 3398 leaves us with 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 669

Going ahead to step 7:
If we divide 536 by 669, we get 0 and a remainder of 536.
Use 0 as the next digit of our solution. 
Result so far: 6850.0
If we take 0 away from 536, we end up with 536.
Bring next digit (9) of the dividend behind the 536 and repeat the process: 5369 / 669

Let's proceed to step 8:
669 can be fit into 5369 8 times, resulting in a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 68508.0
If we take 5352 away from 5369, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
669 can be fit into 170 0 times, resulting in a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 68508.0
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
If we divide 1700 by 669, we get 2 and a remainder of 362.
The next digit of our result is 2. 
Result so far: 68508.02
Subtract 1338 from 1700 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 11:
The number 669 fits into 3620 5 times, leaving a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 68508.025
The remainder is 275 after subtracting 3345 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 12:
When dividing 2750 by 669, we get 4 with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 68508.0254
Subtract 2676 from 2750 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
740 divided by 669 is 1 with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 68508.02541
If we take 669 away from 740, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 14:
If we divide 710 by 669, we get 1 and a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 68508.025411
If we take 669 away from 710, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final result is 68508.025411 with a remainder of 4.1e-06.
