We look at the division of 40395489 by 709 
We're looking to find how many times 709 goes into 40395489.

On to step 1:
709 can be fit into 4 0 times, resulting in 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 (0) from the dividend, attach it to 4 and continue: 40 / 709

Going ahead to step 2:
40 divided by 709 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 709

Moving on to step 3:
403 divided by 709 is 0 with a remainder of 403.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 403 to get 403.
Append the next digit (9) from the dividend to 403 and continue with: 4039 / 709

Step 4:
4039 divided by 709 is 5 with a remainder of 494.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 3545 away from 4039, we end up with 494.
Grab the next digit (5) from the dividend, add it to 494, then carry on: 4945 / 709

Let's proceed to step 5:
When dividing 4945 by 709, we get 6 with a remainder of 691.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we subtract 4254 from 4945, we get 691.
Take the next digit (4) from the dividend and append it to 691, then repeat: 6914 / 709

Let's proceed to step 6:
When dividing 6914 by 709, we get 9 with a remainder of 533.
Use 9 as the next digit of our solution. 
Result so far: 569.0
Subtract 6381 from 6914 to get 533.
Grab the next digit (8) from the dividend, add it to 533, then carry on: 5338 / 709

On to step 7:
If we divide 5338 by 709, we get 7 and a remainder of 375.
Record the quotient 7 as the next digit in the result. 
Result so far: 5697.0
The remainder is 375 after subtracting 4963 from 5338.
Append the next digit (9) from the dividend to 375 and continue with: 3759 / 709

Advancing to step 8:
If we divide 3759 by 709, we get 5 and a remainder of 214.
Use 5 as the next digit of our solution. 
Result so far: 56975.0
If we subtract 3545 from 3759, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 9:
The number 709 fits into 2140 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 56975.3
Subtract 2127 from 2140 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
709 goes into 130 0 times with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 56975.3
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 11:
The number 709 fits into 1300 1 times, leaving a remainder of 591.
Use 1 as the next digit of our solution. 
Result so far: 56975.301
Deduct 709 from 1300 and we're left with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Going ahead to step 12:
709 goes into 5910 8 times with a remainder of 238.
Record the quotient 8 as the next digit in the result. 
Result so far: 56975.3018
The remainder is 238 after subtracting 5672 from 5910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 13:
If we divide 2380 by 709, we get 3 and a remainder of 253.
Record the quotient 3 as the next digit in the result. 
Result so far: 56975.30183
The remainder is 253 after subtracting 2127 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 14:
When dividing 2530 by 709, we get 3 with a remainder of 403.
The next digit of our result is 3. 
Result so far: 56975.301833
If we subtract 2127 from 2530, we get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

The final result is 56975.301833 with a remainder of 4.03e-05.
