We look at the division of 70803991 by 560 
The aim is to understand the frequency of 560 in 70803991.

Advancing to step 1:
560 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 560

Let's proceed to step 2:
560 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 560

Step 3:
If we divide 708 by 560, we get 1 and a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 560 from 708 leaves us with 148.
Append the next digit (0) from the dividend to 148 and continue with: 1480 / 560

Advancing to step 4:
The number 560 fits into 1480 2 times, leaving a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1120 away from 1480, we end up with 360.
Fetch the next digit (3) from the dividend, attach it to 360 and continue: 3603 / 560

On to step 5:
If we divide 3603 by 560, we get 6 and a remainder of 243.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
The remainder is 243 after subtracting 3360 from 3603.
Grab the next digit (9) from the dividend, add it to 243, then carry on: 2439 / 560

On to step 6:
560 goes into 2439 4 times with a remainder of 199.
Use 4 as the next digit of our solution. 
Result so far: 1264.0
Subtract 2240 from 2439 to get 199.
Include the next digit (9) from the dividend after 199, then repeat: 1999 / 560

Step 7:
When dividing 1999 by 560, we get 3 with a remainder of 319.
Record the quotient 3 as the next digit in the result. 
Result so far: 12643.0
If we take 1680 away from 1999, we end up with 319.
Append the next digit (1) from the dividend to 319 and continue with: 3191 / 560

Moving on to step 8:
560 goes into 3191 5 times with a remainder of 391.
Put 5 as the next digit of the answer. 
Result so far: 126435.0
If we subtract 2800 from 3191, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Let's proceed to step 9:
If we divide 3910 by 560, we get 6 and a remainder of 550.
The next digit of our result is 6. 
Result so far: 126435.6
Deduct 3360 from 3910 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 10:
When dividing 5500 by 560, we get 9 with a remainder of 460.
Record the quotient 9 as the next digit in the result. 
Result so far: 126435.69
Subtracting 5040 from 5500 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
When dividing 4600 by 560, we get 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 126435.698
Deduct 4480 from 4600 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
When dividing 1200 by 560, we get 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 126435.6982
Subtract 1120 from 1200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
The number 560 fits into 800 1 times, leaving a remainder of 240.
Record the quotient 1 as the next digit in the result. 
Result so far: 126435.69821
If we subtract 560 from 800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
When dividing 2400 by 560, we get 4 with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 126435.698214
If we take 2240 away from 2400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
1600 divided by 560 is 2 with a remainder of 480.
Use 2 as the next digit of our solution. 
Result so far: 126435.6982142
If we subtract 1120 from 1600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 16:
560 can be fit into 4800 8 times, resulting in a remainder of 320.
The next digit of our result is 8. 
Result so far: 126435.69821428
If we subtract 4480 from 4800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 126435.69821428, with a leftover of 3.2e-07.
