341904 divided by 45 
The aim is to understand the frequency of 45 in 341904.

Advancing to step 1:
The number 45 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 45

Advancing to step 2:
45 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 45

On to step 3:
45 can be fit into 341 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 315 from 341 and we're left with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 45

Going ahead to step 4:
45 can be fit into 269 5 times, resulting in a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we subtract 225 from 269, we get 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 45

Going ahead to step 5:
45 goes into 440 9 times with a remainder of 35.
The next digit of our result is 9. 
Result so far: 759.0
Subtracting 405 from 440 leaves us with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 45

Going ahead to step 6:
The number 45 fits into 354 7 times, leaving a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 7597.0
Subtract 315 from 354 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
When dividing 390 by 45, we get 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 7597.8
If we subtract 360 from 390, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
45 goes into 300 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 7597.86
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
When dividing 300 by 45, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 7597.866
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 7597.866, and the remainder is 0.003.
