We divide 65551719 by 561
The aim is to understand the frequency of 561 in 65551719.

Moving on to step 1:
If we divide 6 by 561, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 561

Going ahead to step 2:
When dividing 65 by 561, we get 0 with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Bring next digit (5) of the dividend behind the 65 and repeat the process: 655 / 561

Step 3:
561 can be fit into 655 1 times, resulting in a remainder of 94.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 561 from 655 and we're left with 94.
Grab the next digit (5) from the dividend, add it to 94, then carry on: 945 / 561

Step 4:
When dividing 945 by 561, we get 1 with a remainder of 384.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 384 after subtracting 561 from 945.
Include the next digit (1) from the dividend after 384, then repeat: 3841 / 561

Advancing to step 5:
3841 divided by 561 is 6 with a remainder of 475.
The next digit of our result is 6. 
Result so far: 116.0
If we take 3366 away from 3841, we end up with 475.
Append the next digit (7) from the dividend to 475 and continue with: 4757 / 561

Advancing to step 6:
The number 561 fits into 4757 8 times, leaving a remainder of 269.
Use 8 as the next digit of our solution. 
Result so far: 1168.0
Subtract 4488 from 4757 to get 269.
Take the next digit (1) from the dividend and append it to 269, then repeat: 2691 / 561

Advancing to step 7:
If we divide 2691 by 561, we get 4 and a remainder of 447.
The number 4 becomes the next digit in our result. 
Result so far: 11684.0
Deduct 2244 from 2691 and we're left with 447.
Include the next digit (9) from the dividend after 447, then repeat: 4479 / 561

Moving on to step 8:
If we divide 4479 by 561, we get 7 and a remainder of 552.
The next digit of our result is 7. 
Result so far: 116847.0
If we subtract 3927 from 4479, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 9:
The number 561 fits into 5520 9 times, leaving a remainder of 471.
Use 9 as the next digit of our solution. 
Result so far: 116847.9
Subtracting 5049 from 5520 leaves us with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Going ahead to step 10:
4710 divided by 561 is 8 with a remainder of 222.
Use 8 as the next digit of our solution. 
Result so far: 116847.98
Subtracting 4488 from 4710 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 11:
2220 divided by 561 is 3 with a remainder of 537.
Use 3 as the next digit of our solution. 
Result so far: 116847.983
If we take 1683 away from 2220, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 12:
When dividing 5370 by 561, we get 9 with a remainder of 321.
Write down 9 as next digit of the result. 
Result so far: 116847.9839
The remainder is 321 after subtracting 5049 from 5370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 13:
561 can be fit into 3210 5 times, resulting in a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 116847.98395
If we take 2805 away from 3210, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 14:
4050 divided by 561 is 7 with a remainder of 123.
Write down 7 as next digit of the result. 
Result so far: 116847.983957
The remainder is 123 after subtracting 3927 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 15:
561 goes into 1230 2 times with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 116847.9839572
If we subtract 1122 from 1230, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 16:
If we divide 1080 by 561, we get 1 and a remainder of 519.
The next digit of our result is 1. 
Result so far: 116847.98395721
If we subtract 561 from 1080, we get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

In conclusion, the division gives 116847.98395721 with a balance of 5.19e-07.
