We're dividing 78151065 by 564 
We want to figure out the number of times 78151065 can be divided by 564.

On to step 1:
If we divide 7 by 564, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 564

Moving on to step 2:
The number 564 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 564

Moving on to step 3:
The number 564 fits into 781 1 times, leaving a remainder of 217.
The next digit of our result is 1. 
Result so far: 1.0
If we take 564 away from 781, we end up with 217.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 564

Step 4:
When dividing 2175 by 564, we get 3 with a remainder of 483.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 483 after subtracting 1692 from 2175.
Take the next digit (1) from the dividend and append it to 483, then repeat: 4831 / 564

On to step 5:
564 goes into 4831 8 times with a remainder of 319.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we subtract 4512 from 4831, we get 319.
Take the next digit (0) from the dividend and append it to 319, then repeat: 3190 / 564

Going ahead to step 6:
564 can be fit into 3190 5 times, resulting in a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 1385.0
Subtract 2820 from 3190 to get 370.
Include the next digit (6) from the dividend after 370, then repeat: 3706 / 564

Let's proceed to step 7:
If we divide 3706 by 564, we get 6 and a remainder of 322.
The number 6 becomes the next digit in our result. 
Result so far: 13856.0
Subtracting 3384 from 3706 leaves us with 322.
Include the next digit (5) from the dividend after 322, then repeat: 3225 / 564

Step 8:
564 can be fit into 3225 5 times, resulting in a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 138565.0
If we take 2820 away from 3225, 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.

On to step 9:
564 can be fit into 4050 7 times, resulting in a remainder of 102.
Use 7 as the next digit of our solution. 
Result so far: 138565.7
Deduct 3948 from 4050 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 10:
The number 564 fits into 1020 1 times, leaving a remainder of 456.
The next digit of our result is 1. 
Result so far: 138565.71
If we take 564 away from 1020, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 11:
4560 divided by 564 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 138565.718
Subtract 4512 from 4560 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
The number 564 fits into 480 0 times, leaving a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 138565.718
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 13:
The number 564 fits into 4800 8 times, leaving a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 138565.71808
Subtracting 4512 from 4800 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 14:
The number 564 fits into 2880 5 times, leaving a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 138565.718085
Subtract 2820 from 2880 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
The number 564 fits into 600 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 138565.7180851
If we subtract 564 from 600, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 16:
If we divide 360 by 564, we get 0 and a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 138565.7180851
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final outcome is 138565.7180851, with a leftover of 3.6e-07.
