Let's divide 39937173 by 520
We want to divide 39937173 by 520.

Moving on to step 1:
520 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 520

Going ahead to step 2:
520 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 520

Step 3:
520 goes into 399 0 times with a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 399 after subtracting 0 from 399.
Take the next digit (3) from the dividend and append it to 399, then repeat: 3993 / 520

Let's proceed to step 4:
520 can be fit into 3993 7 times, resulting in a remainder of 353.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 3640 from 3993 to get 353.
Bring next digit (7) of the dividend behind the 353 and repeat the process: 3537 / 520

Going ahead to step 5:
If we divide 3537 by 520, we get 6 and a remainder of 417.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we subtract 3120 from 3537, we get 417.
Fetch the next digit (1) from the dividend, attach it to 417 and continue: 4171 / 520

On to step 6:
When dividing 4171 by 520, we get 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 768.0
Subtracting 4160 from 4171 leaves us with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 520

Let's proceed to step 7:
520 goes into 117 0 times with a remainder of 117.
The next digit of our result is 0. 
Result so far: 7680.0
If we take 0 away from 117, we end up with 117.
Take the next digit (3) from the dividend and append it to 117, then repeat: 1173 / 520

Let's proceed to step 8:
520 goes into 1173 2 times with a remainder of 133.
Use 2 as the next digit of our solution. 
Result so far: 76802.0
Subtracting 1040 from 1173 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
If we divide 1330 by 520, we get 2 and a remainder of 290.
Use 2 as the next digit of our solution. 
Result so far: 76802.2
If we take 1040 away from 1330, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 10:
If we divide 2900 by 520, we get 5 and a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 76802.25
If we take 2600 away from 2900, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
When dividing 3000 by 520, we get 5 with a remainder of 400.
Write down 5 as next digit of the result. 
Result so far: 76802.255
Subtracting 2600 from 3000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 76802.255, and the remainder is 0.04.
