26125780 divided by 561 
The aim is to understand the frequency of 561 in 26125780.

Let's proceed to step 1:
The number 561 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 561

Moving on to step 2:
561 can be fit into 26 0 times, resulting in a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 561

Moving on to step 3:
If we divide 261 by 561, we get 0 and a remainder of 261.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 261 after subtracting 0 from 261.
Bring next digit (2) of the dividend behind the 261 and repeat the process: 2612 / 561

Step 4:
561 can be fit into 2612 4 times, resulting in a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 368 after subtracting 2244 from 2612.
Fetch the next digit (5) from the dividend, attach it to 368 and continue: 3685 / 561

Moving on to step 5:
If we divide 3685 by 561, we get 6 and a remainder of 319.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we subtract 3366 from 3685, we get 319.
Fetch the next digit (7) from the dividend, attach it to 319 and continue: 3197 / 561

Let's proceed to step 6:
When dividing 3197 by 561, we get 5 with a remainder of 392.
Use 5 as the next digit of our solution. 
Result so far: 465.0
Subtracting 2805 from 3197 leaves us with 392.
Append the next digit (8) from the dividend to 392 and continue with: 3928 / 561

Step 7:
3928 divided by 561 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 4657.0
If we take 3927 away from 3928, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 561

Moving on to step 8:
If we divide 10 by 561, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 46570.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 561, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 46570.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
1000 divided by 561 is 1 with a remainder of 439.
The number 1 becomes the next digit in our result. 
Result so far: 46570.01
The remainder is 439 after subtracting 561 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Moving on to step 11:
The number 561 fits into 4390 7 times, leaving a remainder of 463.
Write down 7 as next digit of the result. 
Result so far: 46570.017
If we take 3927 away from 4390, we end up with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Advancing to step 12:
561 goes into 4630 8 times with a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 46570.0178
If we take 4488 away from 4630, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 13:
561 goes into 1420 2 times with a remainder of 298.
The number 2 becomes the next digit in our result. 
Result so far: 46570.01782
The remainder is 298 after subtracting 1122 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 14:
561 goes into 2980 5 times with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 46570.017825
Deduct 2805 from 2980 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 15:
The number 561 fits into 1750 3 times, leaving a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 46570.0178253
Deduct 1683 from 1750 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 16:
The number 561 fits into 670 1 times, leaving a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 46570.01782531
The remainder is 109 after subtracting 561 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

The quotient of the division is 46570.01782531, and the remainder is 1.09e-07.
