27802043 divided by 45 
The aim is to understand the frequency of 45 in 27802043.

Step 1:
The number 45 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 45

Going ahead to step 2:
27 divided by 45 is 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 45

Moving on to step 3:
The number 45 fits into 278 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 270 away from 278, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 45

Moving on to step 4:
The number 45 fits into 80 1 times, leaving a remainder of 35.
The next digit of our result is 1. 
Result so far: 61.0
Subtracting 45 from 80 leaves us with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 45

Step 5:
45 goes into 352 7 times with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 617.0
The remainder is 37 after subtracting 315 from 352.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 45

Step 6:
370 divided by 45 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 6178.0
If we subtract 360 from 370, we get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 45

Going ahead to step 7:
If we divide 104 by 45, we get 2 and a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 61782.0
Deduct 90 from 104 and we're left with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 45

On to step 8:
If we divide 143 by 45, we get 3 and a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 617823.0
The remainder is 8 after subtracting 135 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
45 goes into 80 1 times with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 617823.1
Subtracting 45 from 80 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
45 goes into 350 7 times with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 617823.17
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 617823.177
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 617823.177, and the remainder is 0.0035.
