49490246 ÷ 561 
The aim is to understand the frequency of 561 in 49490246.

Moving on to step 1:
If we divide 4 by 561, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 561

Advancing to step 2:
49 divided by 561 is 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 561

Step 3:
When dividing 494 by 561, we get 0 with a remainder of 494.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 494, we get 494.
Fetch the next digit (9) from the dividend, attach it to 494 and continue: 4949 / 561

Going ahead to step 4:
4949 divided by 561 is 8 with a remainder of 461.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 4488 away from 4949, we end up with 461.
Append the next digit (0) from the dividend to 461 and continue with: 4610 / 561

On to step 5:
4610 divided by 561 is 8 with a remainder of 122.
The next digit of our result is 8. 
Result so far: 88.0
Subtract 4488 from 4610 to get 122.
Bring next digit (2) of the dividend behind the 122 and repeat the process: 1222 / 561

On to step 6:
If we divide 1222 by 561, we get 2 and a remainder of 100.
Put 2 as the next digit of the answer. 
Result so far: 882.0
Subtracting 1122 from 1222 leaves us with 100.
Append the next digit (4) from the dividend to 100 and continue with: 1004 / 561

Moving on to step 7:
The number 561 fits into 1004 1 times, leaving a remainder of 443.
Use 1 as the next digit of our solution. 
Result so far: 8821.0
The remainder is 443 after subtracting 561 from 1004.
Grab the next digit (6) from the dividend, add it to 443, then carry on: 4436 / 561

On to step 8:
561 goes into 4436 7 times with a remainder of 509.
Use 7 as the next digit of our solution. 
Result so far: 88217.0
The remainder is 509 after subtracting 3927 from 4436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Let's proceed to step 9:
561 can be fit into 5090 9 times, resulting in a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 88217.9
If we take 5049 away from 5090, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
561 can be fit into 410 0 times, resulting in a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 88217.9
Deduct 0 from 410 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 11:
561 goes into 4100 7 times with a remainder of 173.
Use 7 as the next digit of our solution. 
Result so far: 88217.907
Subtract 3927 from 4100 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 12:
561 can be fit into 1730 3 times, resulting in a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 88217.9073
If we take 1683 away from 1730, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 13:
When dividing 470 by 561, we get 0 with a remainder of 470.
Use 0 as the next digit of our solution. 
Result so far: 88217.9073
The remainder is 470 after subtracting 0 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 14:
4700 divided by 561 is 8 with a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 88217.907308
Deduct 4488 from 4700 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 15:
2120 divided by 561 is 3 with a remainder of 437.
The number 3 becomes the next digit in our result. 
Result so far: 88217.9073083
Deduct 1683 from 2120 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 16:
561 can be fit into 4370 7 times, resulting in a remainder of 443.
Record the quotient 7 as the next digit in the result. 
Result so far: 88217.90730837
The remainder is 443 after subtracting 3927 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

The final result is 88217.90730837 with a remainder of 4.43e-07.
