We divide 19964959 by 520
Let's see how many times 520 fits into 19964959.

Advancing to step 1:
If we divide 1 by 520, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 520

Step 2:
If we divide 19 by 520, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 520

Step 3:
520 goes into 199 0 times with a remainder of 199.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 199 after subtracting 0 from 199.
Grab the next digit (6) from the dividend, add it to 199, then carry on: 1996 / 520

Advancing to step 4:
520 can be fit into 1996 3 times, resulting in a remainder of 436.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 1560 from 1996 leaves us with 436.
Fetch the next digit (4) from the dividend, attach it to 436 and continue: 4364 / 520

Let's proceed to step 5:
When dividing 4364 by 520, we get 8 with a remainder of 204.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 4160 from 4364 and we're left with 204.
Take the next digit (9) from the dividend and append it to 204, then repeat: 2049 / 520

Advancing to step 6:
520 can be fit into 2049 3 times, resulting in a remainder of 489.
The next digit of our result is 3. 
Result so far: 383.0
Subtracting 1560 from 2049 leaves us with 489.
Append the next digit (5) from the dividend to 489 and continue with: 4895 / 520

Step 7:
4895 divided by 520 is 9 with a remainder of 215.
Record the quotient 9 as the next digit in the result. 
Result so far: 3839.0
Deduct 4680 from 4895 and we're left with 215.
Append the next digit (9) from the dividend to 215 and continue with: 2159 / 520

Step 8:
If we divide 2159 by 520, we get 4 and a remainder of 79.
Record the quotient 4 as the next digit in the result. 
Result so far: 38394.0
Subtract 2080 from 2159 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 9:
The number 520 fits into 790 1 times, leaving a remainder of 270.
The next digit of our result is 1. 
Result so far: 38394.1
Subtract 520 from 790 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
520 goes into 2700 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 38394.15
If we subtract 2600 from 2700, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
The number 520 fits into 1000 1 times, leaving a remainder of 480.
Write down 1 as next digit of the result. 
Result so far: 38394.151
Deduct 520 from 1000 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 12:
If we divide 4800 by 520, we get 9 and a remainder of 120.
The next digit of our result is 9. 
Result so far: 38394.1519
Subtract 4680 from 4800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
520 can be fit into 1200 2 times, resulting in a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 38394.15192
Subtract 1040 from 1200 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
If we divide 1600 by 520, we get 3 and a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 38394.151923
Subtracting 1560 from 1600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
When dividing 400 by 520, we get 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 38394.151923
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 16:
520 goes into 4000 7 times with a remainder of 360.
Write down 7 as next digit of the result. 
Result so far: 38394.15192307
The remainder is 360 after subtracting 3640 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final outcome is 38394.15192307, with a leftover of 3.6e-07.
