Let's divide 1956903 by 45
The aim is to understand the frequency of 45 in 1956903.

Going ahead to step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 45

Let's proceed to step 2:
The number 45 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 45

Moving on to step 3:
When dividing 195 by 45, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 180 from 195 leaves us with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 45

Going ahead to step 4:
45 can be fit into 156 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 135 from 156 leaves us with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 45

On to step 5:
45 goes into 219 4 times with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
Subtracting 180 from 219 leaves us with 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 45

Let's proceed to step 6:
45 goes into 390 8 times with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 4348.0
Deduct 360 from 390 and we're left with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 45

Moving on to step 7:
If we divide 303 by 45, we get 6 and a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 43486.0
Deduct 270 from 303 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
45 can be fit into 330 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 43486.7
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
If we divide 150 by 45, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 43486.73
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
150 divided by 45 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 43486.733
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 43486.733, with a leftover of 0.0015.
