78037730 ÷ 573 
We want to figure out the number of times 78037730 can be divided by 573.

Step 1:
573 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
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 573

Let's proceed to step 2:
78 divided by 573 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 573

On to step 3:
When dividing 780 by 573, we get 1 with a remainder of 207.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 573 from 780 leaves us with 207.
Include the next digit (3) from the dividend after 207, then repeat: 2073 / 573

Advancing to step 4:
573 can be fit into 2073 3 times, resulting in a remainder of 354.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1719 away from 2073, we end up with 354.
Take the next digit (7) from the dividend and append it to 354, then repeat: 3547 / 573

On to step 5:
573 can be fit into 3547 6 times, resulting in a remainder of 109.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Deduct 3438 from 3547 and we're left with 109.
Include the next digit (7) from the dividend after 109, then repeat: 1097 / 573

Advancing to step 6:
The number 573 fits into 1097 1 times, leaving a remainder of 524.
The next digit of our result is 1. 
Result so far: 1361.0
If we take 573 away from 1097, we end up with 524.
Bring next digit (3) of the dividend behind the 524 and repeat the process: 5243 / 573

Advancing to step 7:
The number 573 fits into 5243 9 times, leaving a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 13619.0
If we subtract 5157 from 5243, we get 86.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 573

Advancing to step 8:
If we divide 860 by 573, we get 1 and a remainder of 287.
Write down 1 as next digit of the result. 
Result so far: 136191.0
Subtract 573 from 860 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 9:
2870 divided by 573 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 136191.5
Deduct 2865 from 2870 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
If we divide 50 by 573, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 136191.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
When dividing 500 by 573, we get 0 with a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 136191.5
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 136191.5 with a remaining 0.05.
