74069509 divided by 520 
We want to divide 74069509 by 520.

Moving on to step 1:
520 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 520

Step 2:
If we divide 74 by 520, we get 0 and a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 520

Advancing to step 3:
740 divided by 520 is 1 with a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 220 after subtracting 520 from 740.
Include the next digit (6) from the dividend after 220, then repeat: 2206 / 520

Let's proceed to step 4:
520 can be fit into 2206 4 times, resulting in a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 2080 from 2206 and we're left with 126.
Fetch the next digit (9) from the dividend, attach it to 126 and continue: 1269 / 520

Moving on to step 5:
If we divide 1269 by 520, we get 2 and a remainder of 229.
Put 2 as the next digit of the answer. 
Result so far: 142.0
The remainder is 229 after subtracting 1040 from 1269.
Grab the next digit (5) from the dividend, add it to 229, then carry on: 2295 / 520

Moving on to step 6:
520 can be fit into 2295 4 times, resulting in a remainder of 215.
Use 4 as the next digit of our solution. 
Result so far: 1424.0
Subtract 2080 from 2295 to get 215.
Bring next digit (0) of the dividend behind the 215 and repeat the process: 2150 / 520

Moving on to step 7:
If we divide 2150 by 520, we get 4 and a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 14244.0
Subtract 2080 from 2150 to get 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 520

Advancing to step 8:
If we divide 709 by 520, we get 1 and a remainder of 189.
The next digit of our result is 1. 
Result so far: 142441.0
If we take 520 away from 709, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 9:
1890 divided by 520 is 3 with a remainder of 330.
The next digit of our result is 3. 
Result so far: 142441.3
The remainder is 330 after subtracting 1560 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
520 can be fit into 3300 6 times, resulting in a remainder of 180.
Write down 6 as next digit of the result. 
Result so far: 142441.36
If we take 3120 away from 3300, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
When dividing 1800 by 520, we get 3 with a remainder of 240.
Write down 3 as next digit of the result. 
Result so far: 142441.363
The remainder is 240 after subtracting 1560 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 12:
When dividing 2400 by 520, we get 4 with a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 142441.3634
Subtract 2080 from 2400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 13:
3200 divided by 520 is 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 142441.36346
If we subtract 3120 from 3200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
If we divide 800 by 520, we get 1 and a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 142441.363461
If we take 520 away from 800, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 15:
When dividing 2800 by 520, we get 5 with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 142441.3634615
Deduct 2600 from 2800 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
When dividing 2000 by 520, we get 3 with a remainder of 440.
Record the quotient 3 as the next digit in the result. 
Result so far: 142441.36346153
If we subtract 1560 from 2000, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 142441.36346153, with a leftover of 4.4e-07.
