We look at the division of 78539803 by 560 
We want to figure out the number of times 78539803 can be divided by 560.

Advancing to step 1:
560 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 560

Going ahead to step 2:
The number 560 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 560

Step 3:
When dividing 785 by 560, we get 1 with a remainder of 225.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 560 from 785 to get 225.
Append the next digit (3) from the dividend to 225 and continue with: 2253 / 560

Moving on to step 4:
The number 560 fits into 2253 4 times, leaving a remainder of 13.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 2240 from 2253 leaves us with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 560

Going ahead to step 5:
139 divided by 560 is 0 with a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtracting 0 from 139 leaves us with 139.
Append the next digit (8) from the dividend to 139 and continue with: 1398 / 560

Let's proceed to step 6:
560 can be fit into 1398 2 times, resulting in a remainder of 278.
Put 2 as the next digit of the answer. 
Result so far: 1402.0
The remainder is 278 after subtracting 1120 from 1398.
Bring next digit (0) of the dividend behind the 278 and repeat the process: 2780 / 560

On to step 7:
When dividing 2780 by 560, we get 4 with a remainder of 540.
Put 4 as the next digit of the answer. 
Result so far: 14024.0
If we take 2240 away from 2780, we end up with 540.
Bring next digit (3) of the dividend behind the 540 and repeat the process: 5403 / 560

Moving on to step 8:
When dividing 5403 by 560, we get 9 with a remainder of 363.
Use 9 as the next digit of our solution. 
Result so far: 140249.0
Deduct 5040 from 5403 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 9:
The number 560 fits into 3630 6 times, leaving a remainder of 270.
Write down 6 as next digit of the result. 
Result so far: 140249.6
Subtract 3360 from 3630 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
When dividing 2700 by 560, we get 4 with a remainder of 460.
Write down 4 as next digit of the result. 
Result so far: 140249.64
Subtract 2240 from 2700 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
When dividing 4600 by 560, we get 8 with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 140249.648
Subtract 4480 from 4600 to get 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:
560 can be fit into 1200 2 times, resulting in a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 140249.6482
If we subtract 1120 from 1200, we 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.

Step 13:
560 goes into 800 1 times with a remainder of 240.
The next digit of our result is 1. 
Result so far: 140249.64821
If we take 560 away from 800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
560 can be fit into 2400 4 times, resulting in a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 140249.648214
Subtracting 2240 from 2400 leaves us 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.

Let's proceed to step 15:
1600 divided by 560 is 2 with a remainder of 480.
Write down 2 as next digit of the result. 
Result so far: 140249.6482142
If we take 1120 away from 1600, we end up 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 16:
560 goes into 4800 8 times with a remainder of 320.
The number 8 becomes the next digit in our result. 
Result so far: 140249.64821428
Subtract 4480 from 4800 to 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.

Our division results in 140249.64821428 with a remaining 3.2e-07.
