42074466 ÷ 520 
We're looking to find how many times 520 goes into 42074466.

On to step 1:
The number 520 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 520

Let's proceed to step 2:
If we divide 42 by 520, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 520

Let's proceed to step 3:
520 goes into 420 0 times with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 420 after subtracting 0 from 420.
Fetch the next digit (7) from the dividend, attach it to 420 and continue: 4207 / 520

Let's proceed to step 4:
If we divide 4207 by 520, we get 8 and a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 4160 from 4207, we get 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 520

Let's proceed to step 5:
474 divided by 520 is 0 with a remainder of 474.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 474 leaves us with 474.
Append the next digit (4) from the dividend to 474 and continue with: 4744 / 520

On to step 6:
4744 divided by 520 is 9 with a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 809.0
Subtracting 4680 from 4744 leaves us with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 520

Going ahead to step 7:
If we divide 646 by 520, we get 1 and a remainder of 126.
Put 1 as the next digit of the answer. 
Result so far: 8091.0
The remainder is 126 after subtracting 520 from 646.
Include the next digit (6) from the dividend after 126, then repeat: 1266 / 520

On to step 8:
1266 divided by 520 is 2 with a remainder of 226.
Write down 2 as next digit of the result. 
Result so far: 80912.0
Subtracting 1040 from 1266 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 9:
If we divide 2260 by 520, we get 4 and a remainder of 180.
Use 4 as the next digit of our solution. 
Result so far: 80912.4
If we subtract 2080 from 2260, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
520 goes into 1800 3 times with a remainder of 240.
Put 3 as the next digit of the answer. 
Result so far: 80912.43
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.

Moving on to step 11:
When dividing 2400 by 520, we get 4 with a remainder of 320.
The next digit of our result is 4. 
Result so far: 80912.434
Deduct 2080 from 2400 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 12:
520 can be fit into 3200 6 times, resulting in a remainder of 80.
The next digit of our result is 6. 
Result so far: 80912.4346
Subtracting 3120 from 3200 leaves us with 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 13:
If we divide 800 by 520, we get 1 and a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 80912.43461
The remainder is 280 after subtracting 520 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 14:
520 can be fit into 2800 5 times, resulting in a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 80912.434615
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.

Advancing to step 15:
The number 520 fits into 2000 3 times, leaving a remainder of 440.
The next digit of our result is 3. 
Result so far: 80912.4346153
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.

Step 16:
The number 520 fits into 4400 8 times, leaving a remainder of 240.
The next digit of our result is 8. 
Result so far: 80912.43461538
If we subtract 4160 from 4400, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 80912.43461538 and a remainder of 2.4e-07.
