We divide 40448497 by 561
The aim is to understand the frequency of 561 in 40448497.

Step 1:
The number 561 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 561

Going ahead to step 2:
40 divided by 561 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 561

Moving on to step 3:
404 divided by 561 is 0 with a remainder of 404.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 404 after subtracting 0 from 404.
Append the next digit (4) from the dividend to 404 and continue with: 4044 / 561

Let's proceed to step 4:
561 goes into 4044 7 times with a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 3927 away from 4044, we end up with 117.
Fetch the next digit (8) from the dividend, attach it to 117 and continue: 1178 / 561

Let's proceed to step 5:
If we divide 1178 by 561, we get 2 and a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 56 after subtracting 1122 from 1178.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 561

Let's proceed to step 6:
When dividing 564 by 561, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 721.0
The remainder is 3 after subtracting 561 from 564.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 561

Let's proceed to step 7:
39 divided by 561 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 7210.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 561

Advancing to step 8:
397 divided by 561 is 0 with a remainder of 397.
The number 0 becomes the next digit in our result. 
Result so far: 72100.0
The remainder is 397 after subtracting 0 from 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 9:
The number 561 fits into 3970 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 72100.7
Subtracting 3927 from 3970 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 10:
When dividing 430 by 561, we get 0 with a remainder of 430.
Write down 0 as next digit of the result. 
Result so far: 72100.7
Subtracting 0 from 430 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 11:
If we divide 4300 by 561, we get 7 and a remainder of 373.
Write down 7 as next digit of the result. 
Result so far: 72100.707
Subtract 3927 from 4300 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 12:
When dividing 3730 by 561, we get 6 with a remainder of 364.
The number 6 becomes the next digit in our result. 
Result so far: 72100.7076
If we take 3366 away from 3730, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 13:
3640 divided by 561 is 6 with a remainder of 274.
Put 6 as the next digit of the answer. 
Result so far: 72100.70766
The remainder is 274 after subtracting 3366 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

The final result is 72100.70766 with a remainder of 0.000274.
