39350809 divided by 526 
Our goal is to divide 39350809 by 526.

On to step 1:
3 divided by 526 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 526

On to step 2:
The number 526 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 526

Moving on to step 3:
If we divide 393 by 526, we get 0 and a remainder of 393.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 393, we get 393.
Append the next digit (5) from the dividend to 393 and continue with: 3935 / 526

Going ahead to step 4:
When dividing 3935 by 526, we get 7 with a remainder of 253.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 3682 from 3935 leaves us with 253.
Bring next digit (0) of the dividend behind the 253 and repeat the process: 2530 / 526

Let's proceed to step 5:
2530 divided by 526 is 4 with a remainder of 426.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we take 2104 away from 2530, we end up with 426.
Bring next digit (8) of the dividend behind the 426 and repeat the process: 4268 / 526

On to step 6:
526 can be fit into 4268 8 times, resulting in a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 748.0
If we subtract 4208 from 4268, we get 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 526

Let's proceed to step 7:
The number 526 fits into 600 1 times, leaving a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 7481.0
Deduct 526 from 600 and we're left with 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 526

Step 8:
526 can be fit into 749 1 times, resulting in a remainder of 223.
The next digit of our result is 1. 
Result so far: 74811.0
Subtract 526 from 749 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 9:
526 goes into 2230 4 times with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 74811.4
Subtract 2104 from 2230 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 10:
If we divide 1260 by 526, we get 2 and a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 74811.42
Subtract 1052 from 1260 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 11:
When dividing 2080 by 526, we get 3 with a remainder of 502.
Record the quotient 3 as the next digit in the result. 
Result so far: 74811.423
If we subtract 1578 from 2080, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

On to step 12:
526 goes into 5020 9 times with a remainder of 286.
Write down 9 as next digit of the result. 
Result so far: 74811.4239
Subtracting 4734 from 5020 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 13:
The number 526 fits into 2860 5 times, leaving a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 74811.42395
The remainder is 230 after subtracting 2630 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 14:
526 can be fit into 2300 4 times, resulting in a remainder of 196.
Record the quotient 4 as the next digit in the result. 
Result so far: 74811.423954
If we subtract 2104 from 2300, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 15:
526 goes into 1960 3 times with a remainder of 382.
The next digit of our result is 3. 
Result so far: 74811.4239543
If we take 1578 away from 1960, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 16:
526 can be fit into 3820 7 times, resulting in a remainder of 138.
Record the quotient 7 as the next digit in the result. 
Result so far: 74811.42395437
The remainder is 138 after subtracting 3682 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

In conclusion, the division gives 74811.42395437 with a balance of 1.38e-07.
