We're dividing 156190 by 45 
The aim is to understand the frequency of 45 in 156190.

Going ahead to step 1:
1 divided by 45 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 45

Let's proceed to step 2:
When dividing 15 by 45, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 45

Let's proceed to step 3:
The number 45 fits into 156 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 135 from 156 to get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 45

Moving on to step 4:
If we divide 211 by 45, we get 4 and a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 34.0
The remainder is 31 after subtracting 180 from 211.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 45

Moving on to step 5:
The number 45 fits into 319 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 347.0
Subtracting 315 from 319 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 45

Moving on to step 6:
If we divide 40 by 45, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3470.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
400 divided by 45 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 3470.8
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 45 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 3470.88
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 3470.88, with a leftover of 0.04.
