We look at the division of 85399654 by 520 
We want to divide 85399654 by 520.

Moving on to step 1:
8 divided by 520 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 520

Let's proceed to step 2:
520 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Include the next digit (3) from the dividend after 85, then repeat: 853 / 520

Let's proceed to step 3:
When dividing 853 by 520, we get 1 with a remainder of 333.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 520 from 853 leaves us with 333.
Bring next digit (9) of the dividend behind the 333 and repeat the process: 3339 / 520

Let's proceed to step 4:
520 can be fit into 3339 6 times, resulting in a remainder of 219.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 3120 from 3339 to get 219.
Include the next digit (9) from the dividend after 219, then repeat: 2199 / 520

Let's proceed to step 5:
520 goes into 2199 4 times with a remainder of 119.
The next digit of our result is 4. 
Result so far: 164.0
Deduct 2080 from 2199 and we're left with 119.
Take the next digit (6) from the dividend and append it to 119, then repeat: 1196 / 520

Moving on to step 6:
1196 divided by 520 is 2 with a remainder of 156.
The next digit of our result is 2. 
Result so far: 1642.0
The remainder is 156 after subtracting 1040 from 1196.
Include the next digit (5) from the dividend after 156, then repeat: 1565 / 520

Moving on to step 7:
520 can be fit into 1565 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 16423.0
Subtract 1560 from 1565 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 520

On to step 8:
520 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 164230.0
Subtracting 0 from 54 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
When dividing 540 by 520, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 164230.1
Deduct 520 from 540 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
The number 520 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 164230.1
Deduct 0 from 200 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 11:
2000 divided by 520 is 3 with a remainder of 440.
The next digit of our result is 3. 
Result so far: 164230.103
Deduct 1560 from 2000 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
When dividing 4400 by 520, we get 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 164230.1038
Deduct 4160 from 4400 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
If we divide 2400 by 520, we get 4 and a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 164230.10384
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.

Going ahead to step 14:
520 can be fit into 3200 6 times, resulting in a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 164230.103846
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.

Step 15:
When dividing 800 by 520, we get 1 with a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 164230.1038461
Deduct 520 from 800 and we're left 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.

Advancing to step 16:
The number 520 fits into 2800 5 times, leaving a remainder of 200.
The next digit of our result is 5. 
Result so far: 164230.10384615
Subtracting 2600 from 2800 leaves us 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.

The quotient of the division is 164230.10384615, and the remainder is 2e-07.
