We look at the division of 43072870 by 578 
Our goal is to divide 43072870 by 578.

Moving on to step 1:
The number 578 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 578

Going ahead to step 2:
578 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 578

Advancing to step 3:
578 can be fit into 430 0 times, resulting in a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 430, we end up with 430.
Bring next digit (7) of the dividend behind the 430 and repeat the process: 4307 / 578

Going ahead to step 4:
578 can be fit into 4307 7 times, resulting in a remainder of 261.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 261 after subtracting 4046 from 4307.
Bring next digit (2) of the dividend behind the 261 and repeat the process: 2612 / 578

Let's proceed to step 5:
2612 divided by 578 is 4 with a remainder of 300.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Deduct 2312 from 2612 and we're left with 300.
Append the next digit (8) from the dividend to 300 and continue with: 3008 / 578

On to step 6:
578 can be fit into 3008 5 times, resulting in a remainder of 118.
Put 5 as the next digit of the answer. 
Result so far: 745.0
If we take 2890 away from 3008, we end up with 118.
Take the next digit (7) from the dividend and append it to 118, then repeat: 1187 / 578

Moving on to step 7:
1187 divided by 578 is 2 with a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 7452.0
If we subtract 1156 from 1187, we get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 578

On to step 8:
The number 578 fits into 310 0 times, leaving a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 74520.0
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 9:
The number 578 fits into 3100 5 times, leaving a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 74520.5
Subtract 2890 from 3100 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
When dividing 2100 by 578, we get 3 with a remainder of 366.
The number 3 becomes the next digit in our result. 
Result so far: 74520.53
Subtracting 1734 from 2100 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 11:
578 can be fit into 3660 6 times, resulting in a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 74520.536
If we subtract 3468 from 3660, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 12:
1920 divided by 578 is 3 with a remainder of 186.
The number 3 becomes the next digit in our result. 
Result so far: 74520.5363
If we take 1734 away from 1920, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 13:
578 goes into 1860 3 times with a remainder of 126.
Record the quotient 3 as the next digit in the result. 
Result so far: 74520.53633
Subtracting 1734 from 1860 leaves us 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.

After the division, we end up with 74520.53633 and a remainder of 0.000126.
