We're dividing 74777720 by 578 
Let's see how many times 578 fits into 74777720.

Step 1:
7 divided by 578 is 0 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.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 578

Step 2:
If we divide 74 by 578, we get 0 and a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Grab the next digit (7) from the dividend, add it to 74, then carry on: 747 / 578

Step 3:
If we divide 747 by 578, we get 1 and a remainder of 169.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 578 from 747, we get 169.
Append the next digit (7) from the dividend to 169 and continue with: 1697 / 578

Going ahead to step 4:
If we divide 1697 by 578, we get 2 and a remainder of 541.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1156 from 1697 and we're left with 541.
Append the next digit (7) from the dividend to 541 and continue with: 5417 / 578

Moving on to step 5:
578 can be fit into 5417 9 times, resulting in a remainder of 215.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtracting 5202 from 5417 leaves us with 215.
Grab the next digit (7) from the dividend, add it to 215, then carry on: 2157 / 578

Let's proceed to step 6:
578 goes into 2157 3 times with a remainder of 423.
Write down 3 as next digit of the result. 
Result so far: 1293.0
The remainder is 423 after subtracting 1734 from 2157.
Bring next digit (2) of the dividend behind the 423 and repeat the process: 4232 / 578

Moving on to step 7:
The number 578 fits into 4232 7 times, leaving a remainder of 186.
Put 7 as the next digit of the answer. 
Result so far: 12937.0
If we take 4046 away from 4232, we end up with 186.
Fetch the next digit (0) from the dividend, attach it to 186 and continue: 1860 / 578

Step 8:
If we divide 1860 by 578, we get 3 and a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 129373.0
Deduct 1734 from 1860 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 9:
1260 divided by 578 is 2 with a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 129373.2
The remainder is 104 after subtracting 1156 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 10:
578 goes into 1040 1 times with a remainder of 462.
The number 1 becomes the next digit in our result. 
Result so far: 129373.21
If we subtract 578 from 1040, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Going ahead to step 11:
When dividing 4620 by 578, we get 7 with a remainder of 574.
Use 7 as the next digit of our solution. 
Result so far: 129373.217
If we take 4046 away from 4620, we end up with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 12:
If we divide 5740 by 578, we get 9 and a remainder of 538.
The number 9 becomes the next digit in our result. 
Result so far: 129373.2179
If we take 5202 away from 5740, we end up with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Let's proceed to step 13:
578 can be fit into 5380 9 times, resulting in a remainder of 178.
The next digit of our result is 9. 
Result so far: 129373.21799
Subtract 5202 from 5380 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The quotient of the division is 129373.21799, and the remainder is 0.000178.
