39239370 divided by 521 
Our goal is to divide 39239370 by 521.

Advancing to step 1:
When dividing 3 by 521, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 521

Moving on to step 2:
The number 521 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 521

Let's proceed to step 3:
521 can be fit into 392 0 times, resulting in a remainder of 392.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 392 after subtracting 0 from 392.
Fetch the next digit (3) from the dividend, attach it to 392 and continue: 3923 / 521

Advancing to step 4:
521 can be fit into 3923 7 times, resulting in a remainder of 276.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 3647 from 3923, we get 276.
Grab the next digit (9) from the dividend, add it to 276, then carry on: 2769 / 521

Advancing to step 5:
When dividing 2769 by 521, we get 5 with a remainder of 164.
Write down 5 as next digit of the result. 
Result so far: 75.0
Deduct 2605 from 2769 and we're left with 164.
Grab the next digit (3) from the dividend, add it to 164, then carry on: 1643 / 521

Moving on to step 6:
When dividing 1643 by 521, we get 3 with a remainder of 80.
The number 3 becomes the next digit in our result. 
Result so far: 753.0
Subtract 1563 from 1643 to get 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 521

Let's proceed to step 7:
521 can be fit into 807 1 times, resulting in a remainder of 286.
Use 1 as the next digit of our solution. 
Result so far: 7531.0
Subtract 521 from 807 to get 286.
Bring next digit (0) of the dividend behind the 286 and repeat the process: 2860 / 521

Moving on to step 8:
521 goes into 2860 5 times with a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 75315.0
Subtracting 2605 from 2860 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 9:
The number 521 fits into 2550 4 times, leaving a remainder of 466.
The number 4 becomes the next digit in our result. 
Result so far: 75315.4
If we subtract 2084 from 2550, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 10:
The number 521 fits into 4660 8 times, leaving a remainder of 492.
Write down 8 as next digit of the result. 
Result so far: 75315.48
Deduct 4168 from 4660 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 11:
4920 divided by 521 is 9 with a remainder of 231.
Write down 9 as next digit of the result. 
Result so far: 75315.489
Deduct 4689 from 4920 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 12:
The number 521 fits into 2310 4 times, leaving a remainder of 226.
Put 4 as the next digit of the answer. 
Result so far: 75315.4894
Subtract 2084 from 2310 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 13:
521 can be fit into 2260 4 times, resulting in a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 75315.48944
If we subtract 2084 from 2260, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 75315.48944 with a balance of 0.000176.
