43689410 divided by 578 
We want to divide 43689410 by 578.

Going ahead to step 1:
If we divide 4 by 578, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 578

Step 2:
When dividing 43 by 578, we get 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 578

Advancing to step 3:
When dividing 436 by 578, we get 0 with a remainder of 436.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 436, we end up with 436.
Include the next digit (8) from the dividend after 436, then repeat: 4368 / 578

Going ahead to step 4:
4368 divided by 578 is 7 with a remainder of 322.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 4046 from 4368 to get 322.
Take the next digit (9) from the dividend and append it to 322, then repeat: 3229 / 578

Advancing to step 5:
If we divide 3229 by 578, we get 5 and a remainder of 339.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 2890 from 3229 and we're left with 339.
Take the next digit (4) from the dividend and append it to 339, then repeat: 3394 / 578

Let's proceed to step 6:
If we divide 3394 by 578, we get 5 and a remainder of 504.
Put 5 as the next digit of the answer. 
Result so far: 755.0
Deduct 2890 from 3394 and we're left with 504.
Append the next digit (1) from the dividend to 504 and continue with: 5041 / 578

On to step 7:
578 can be fit into 5041 8 times, resulting in a remainder of 417.
Put 8 as the next digit of the answer. 
Result so far: 7558.0
If we take 4624 away from 5041, we end up with 417.
Append the next digit (0) from the dividend to 417 and continue with: 4170 / 578

Let's proceed to step 8:
4170 divided by 578 is 7 with a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 75587.0
The remainder is 124 after subtracting 4046 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 9:
The number 578 fits into 1240 2 times, leaving a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 75587.2
Deduct 1156 from 1240 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
578 can be fit into 840 1 times, resulting in a remainder of 262.
Put 1 as the next digit of the answer. 
Result so far: 75587.21
Subtracting 578 from 840 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 11:
The number 578 fits into 2620 4 times, leaving a remainder of 308.
Put 4 as the next digit of the answer. 
Result so far: 75587.214
If we take 2312 away from 2620, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 12:
3080 divided by 578 is 5 with a remainder of 190.
The next digit of our result is 5. 
Result so far: 75587.2145
Subtracting 2890 from 3080 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 13:
The number 578 fits into 1900 3 times, leaving a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 75587.21453
Subtract 1734 from 1900 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 14:
If we divide 1660 by 578, we get 2 and a remainder of 504.
The next digit of our result is 2. 
Result so far: 75587.214532
Deduct 1156 from 1660 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 15:
If we divide 5040 by 578, we get 8 and a remainder of 416.
The number 8 becomes the next digit in our result. 
Result so far: 75587.2145328
Subtract 4624 from 5040 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 16:
578 goes into 4160 7 times with a remainder of 114.
The next digit of our result is 7. 
Result so far: 75587.21453287
Deduct 4046 from 4160 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

In conclusion, the division gives 75587.21453287 with a balance of 1.14e-07.
