We're dividing 12642940 by 569 
We want to figure out the number of times 12642940 can be divided by 569.

Let's proceed to step 1:
If we divide 1 by 569, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 569

Moving on to step 2:
569 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 569

Going ahead to step 3:
The number 569 fits into 126 0 times, leaving a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Include the next digit (4) from the dividend after 126, then repeat: 1264 / 569

On to step 4:
1264 divided by 569 is 2 with a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1138 away from 1264, we end up with 126.
Include the next digit (2) from the dividend after 126, then repeat: 1262 / 569

Advancing to step 5:
1262 divided by 569 is 2 with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 1138 from 1262 to get 124.
Take the next digit (9) from the dividend and append it to 124, then repeat: 1249 / 569

Moving on to step 6:
If we divide 1249 by 569, we get 2 and a remainder of 111.
Use 2 as the next digit of our solution. 
Result so far: 222.0
The remainder is 111 after subtracting 1138 from 1249.
Include the next digit (4) from the dividend after 111, then repeat: 1114 / 569

Step 7:
1114 divided by 569 is 1 with a remainder of 545.
The number 1 becomes the next digit in our result. 
Result so far: 2221.0
Subtract 569 from 1114 to get 545.
Include the next digit (0) from the dividend after 545, then repeat: 5450 / 569

Advancing to step 8:
The number 569 fits into 5450 9 times, leaving a remainder of 329.
Use 9 as the next digit of our solution. 
Result so far: 22219.0
If we subtract 5121 from 5450, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 9:
569 goes into 3290 5 times with a remainder of 445.
The number 5 becomes the next digit in our result. 
Result so far: 22219.5
Subtracting 2845 from 3290 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 10:
569 goes into 4450 7 times with a remainder of 467.
The number 7 becomes the next digit in our result. 
Result so far: 22219.57
Subtracting 3983 from 4450 leaves us with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Advancing to step 11:
4670 divided by 569 is 8 with a remainder of 118.
Put 8 as the next digit of the answer. 
Result so far: 22219.578
The remainder is 118 after subtracting 4552 from 4670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 12:
If we divide 1180 by 569, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 22219.5782
Subtracting 1138 from 1180 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
569 can be fit into 420 0 times, resulting in a remainder of 420.
The next digit of our result is 0. 
Result so far: 22219.5782
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 14:
569 goes into 4200 7 times with a remainder of 217.
The number 7 becomes the next digit in our result. 
Result so far: 22219.578207
Subtracting 3983 from 4200 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 15:
569 goes into 2170 3 times with a remainder of 463.
The number 3 becomes the next digit in our result. 
Result so far: 22219.5782073
Subtract 1707 from 2170 to get 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 16:
When dividing 4630 by 569, we get 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 22219.57820738
If we take 4552 away from 4630, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 22219.57820738, with a leftover of 7.8e-08.
