We divide 68123572 by 561
The aim is to understand the frequency of 561 in 68123572.

Advancing to step 1:
561 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 561

Going ahead to step 2:
561 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 561

On to step 3:
561 can be fit into 681 1 times, resulting in a remainder of 120.
The next digit of our result is 1. 
Result so far: 1.0
If we take 561 away from 681, we end up with 120.
Take the next digit (2) from the dividend and append it to 120, then repeat: 1202 / 561

Step 4:
If we divide 1202 by 561, we get 2 and a remainder of 80.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1122 from 1202 to get 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 561

Moving on to step 5:
803 divided by 561 is 1 with a remainder of 242.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtract 561 from 803 to get 242.
Take the next digit (5) from the dividend and append it to 242, then repeat: 2425 / 561

Advancing to step 6:
561 can be fit into 2425 4 times, resulting in a remainder of 181.
Use 4 as the next digit of our solution. 
Result so far: 1214.0
If we subtract 2244 from 2425, we get 181.
Fetch the next digit (7) from the dividend, attach it to 181 and continue: 1817 / 561

On to step 7:
561 goes into 1817 3 times with a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 12143.0
Deduct 1683 from 1817 and we're left with 134.
Append the next digit (2) from the dividend to 134 and continue with: 1342 / 561

Going ahead to step 8:
561 can be fit into 1342 2 times, resulting in a remainder of 220.
The next digit of our result is 2. 
Result so far: 121432.0
If we subtract 1122 from 1342, we get 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 9:
If we divide 2200 by 561, we get 3 and a remainder of 517.
Use 3 as the next digit of our solution. 
Result so far: 121432.3
Deduct 1683 from 2200 and we're left with 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 10:
When dividing 5170 by 561, we get 9 with a remainder of 121.
The number 9 becomes the next digit in our result. 
Result so far: 121432.39
If we take 5049 away from 5170, we end up with 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 11:
1210 divided by 561 is 2 with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 121432.392
The remainder is 88 after subtracting 1122 from 1210.
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 12:
When dividing 880 by 561, we get 1 with a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 121432.3921
Deduct 561 from 880 and we're left 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.

Moving on to step 13:
561 goes into 3190 5 times with a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 121432.39215
If we take 2805 away from 3190, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 14:
The number 561 fits into 3850 6 times, leaving a remainder of 484.
Record the quotient 6 as the next digit in the result. 
Result so far: 121432.392156
Deduct 3366 from 3850 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 15:
4840 divided by 561 is 8 with a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 121432.3921568
The remainder is 352 after subtracting 4488 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 16:
When dividing 3520 by 561, we get 6 with a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 121432.39215686
The remainder is 154 after subtracting 3366 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 121432.39215686 with a remainder of 1.54e-07.
