Let's divide 741871 by 45
The aim is to understand the frequency of 45 in 741871.

On to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 45

Advancing to step 2:
The number 45 fits into 74 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 45 away from 74, we end up with 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 45

Moving on to step 3:
When dividing 291 by 45, we get 6 with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 270 from 291 and we're left with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 45

Let's proceed to step 4:
45 goes into 218 4 times with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Subtracting 180 from 218 leaves us with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 45

On to step 5:
The number 45 fits into 387 8 times, leaving a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 1648.0
Deduct 360 from 387 and we're left with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 45

Moving on to step 6:
If we divide 271 by 45, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 16486.0
Deduct 270 from 271 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 45 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 16486.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
45 goes into 100 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 16486.02
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 45, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 16486.022
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 16486.022, and the remainder is 0.001.
