We're dividing 58491134 by 561 
The aim is to understand the frequency of 561 in 58491134.

Going ahead to step 1:
5 divided by 561 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 561

Step 2:
The number 561 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 561

Let's proceed to step 3:
561 can be fit into 584 1 times, resulting in a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 23 after subtracting 561 from 584.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 561

On to step 4:
561 can be fit into 239 0 times, resulting in a remainder of 239.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 239 to get 239.
Grab the next digit (1) from the dividend, add it to 239, then carry on: 2391 / 561

Advancing to step 5:
When dividing 2391 by 561, we get 4 with a remainder of 147.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtracting 2244 from 2391 leaves us with 147.
Grab the next digit (1) from the dividend, add it to 147, then carry on: 1471 / 561

Advancing to step 6:
1471 divided by 561 is 2 with a remainder of 349.
Record the quotient 2 as the next digit in the result. 
Result so far: 1042.0
Deduct 1122 from 1471 and we're left with 349.
Fetch the next digit (3) from the dividend, attach it to 349 and continue: 3493 / 561

Advancing to step 7:
561 can be fit into 3493 6 times, resulting in a remainder of 127.
Use 6 as the next digit of our solution. 
Result so far: 10426.0
Deduct 3366 from 3493 and we're left with 127.
Include the next digit (4) from the dividend after 127, then repeat: 1274 / 561

Going ahead to step 8:
1274 divided by 561 is 2 with a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 104262.0
Subtracting 1122 from 1274 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 9:
The number 561 fits into 1520 2 times, leaving a remainder of 398.
Put 2 as the next digit of the answer. 
Result so far: 104262.2
The remainder is 398 after subtracting 1122 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 10:
561 can be fit into 3980 7 times, resulting in a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 104262.27
If we take 3927 away from 3980, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 11:
When dividing 530 by 561, we get 0 with a remainder of 530.
Record the quotient 0 as the next digit in the result. 
Result so far: 104262.27
The remainder is 530 after subtracting 0 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 12:
5300 divided by 561 is 9 with a remainder of 251.
Record the quotient 9 as the next digit in the result. 
Result so far: 104262.2709
Subtract 5049 from 5300 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 13:
When dividing 2510 by 561, we get 4 with a remainder of 266.
The number 4 becomes the next digit in our result. 
Result so far: 104262.27094
Subtracting 2244 from 2510 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 14:
When dividing 2660 by 561, we get 4 with a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 104262.270944
Subtracting 2244 from 2660 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

After the division, we end up with 104262.270944 and a remainder of 4.16e-05.
