We divide 78055285 by 561
The aim is to understand the frequency of 561 in 78055285.

Going ahead to step 1:
When dividing 7 by 561, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 561

On to step 2:
The number 561 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 561

Moving on to step 3:
If we divide 780 by 561, we get 1 and a remainder of 219.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 219 after subtracting 561 from 780.
Grab the next digit (5) from the dividend, add it to 219, then carry on: 2195 / 561

Let's proceed to step 4:
2195 divided by 561 is 3 with a remainder of 512.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 512 after subtracting 1683 from 2195.
Append the next digit (5) from the dividend to 512 and continue with: 5125 / 561

Moving on to step 5:
5125 divided by 561 is 9 with a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 139.0
The remainder is 76 after subtracting 5049 from 5125.
Take the next digit (2) from the dividend and append it to 76, then repeat: 762 / 561

On to step 6:
762 divided by 561 is 1 with a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 1391.0
If we take 561 away from 762, we end up with 201.
Bring next digit (8) of the dividend behind the 201 and repeat the process: 2018 / 561

Advancing to step 7:
561 can be fit into 2018 3 times, resulting in a remainder of 335.
Use 3 as the next digit of our solution. 
Result so far: 13913.0
Deduct 1683 from 2018 and we're left with 335.
Fetch the next digit (5) from the dividend, attach it to 335 and continue: 3355 / 561

On to step 8:
3355 divided by 561 is 5 with a remainder of 550.
The next digit of our result is 5. 
Result so far: 139135.0
The remainder is 550 after subtracting 2805 from 3355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 9:
561 goes into 5500 9 times with a remainder of 451.
Put 9 as the next digit of the answer. 
Result so far: 139135.9
Subtract 5049 from 5500 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Moving on to step 10:
If we divide 4510 by 561, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 139135.98
Deduct 4488 from 4510 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
When dividing 220 by 561, we get 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 139135.98
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
561 can be fit into 2200 3 times, resulting in a remainder of 517.
The number 3 becomes the next digit in our result. 
Result so far: 139135.9803
Subtract 1683 from 2200 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

On to step 13:
If we divide 5170 by 561, we get 9 and a remainder of 121.
Use 9 as the next digit of our solution. 
Result so far: 139135.98039
Subtract 5049 from 5170 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 14:
1210 divided by 561 is 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 139135.980392
Deduct 1122 from 1210 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 15:
If we divide 880 by 561, we get 1 and a remainder of 319.
Write down 1 as next digit of the result. 
Result so far: 139135.9803921
Subtracting 561 from 880 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Let's proceed to step 16:
The number 561 fits into 3190 5 times, leaving a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 139135.98039215
If we subtract 2805 from 3190, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Our division results in 139135.98039215 with a remaining 3.85e-07.
