We divide 85901648 by 520
We're looking to find how many times 520 goes into 85901648.

Step 1:
When dividing 8 by 520, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 520

Advancing to step 2:
If we divide 85 by 520, we get 0 and a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 520

Step 3:
859 divided by 520 is 1 with a remainder of 339.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 520 from 859, we get 339.
Append the next digit (0) from the dividend to 339 and continue with: 3390 / 520

Moving on to step 4:
520 can be fit into 3390 6 times, resulting in a remainder of 270.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 270 after subtracting 3120 from 3390.
Bring next digit (1) of the dividend behind the 270 and repeat the process: 2701 / 520

Let's proceed to step 5:
2701 divided by 520 is 5 with a remainder of 101.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
Subtract 2600 from 2701 to get 101.
Bring next digit (6) of the dividend behind the 101 and repeat the process: 1016 / 520

On to step 6:
When dividing 1016 by 520, we get 1 with a remainder of 496.
Put 1 as the next digit of the answer. 
Result so far: 1651.0
Deduct 520 from 1016 and we're left with 496.
Take the next digit (4) from the dividend and append it to 496, then repeat: 4964 / 520

Advancing to step 7:
If we divide 4964 by 520, we get 9 and a remainder of 284.
Record the quotient 9 as the next digit in the result. 
Result so far: 16519.0
Subtract 4680 from 4964 to get 284.
Bring next digit (8) of the dividend behind the 284 and repeat the process: 2848 / 520

Let's proceed to step 8:
2848 divided by 520 is 5 with a remainder of 248.
Put 5 as the next digit of the answer. 
Result so far: 165195.0
If we subtract 2600 from 2848, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 9:
520 can be fit into 2480 4 times, resulting in a remainder of 400.
Put 4 as the next digit of the answer. 
Result so far: 165195.4
If we take 2080 away from 2480, we end up 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.

Going ahead to step 10:
The number 520 fits into 4000 7 times, leaving a remainder of 360.
Record the quotient 7 as the next digit in the result. 
Result so far: 165195.47
Deduct 3640 from 4000 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
520 can be fit into 3600 6 times, resulting in a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 165195.476
Subtracting 3120 from 3600 leaves us 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.

Step 12:
The number 520 fits into 4800 9 times, leaving a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 165195.4769
Deduct 4680 from 4800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
When dividing 1200 by 520, we get 2 with a remainder of 160.
The next digit of our result is 2. 
Result so far: 165195.47692
If we take 1040 away from 1200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
The number 520 fits into 1600 3 times, leaving a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 165195.476923
Subtract 1560 from 1600 to get 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:
If we divide 400 by 520, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 165195.476923
If we take 0 away from 400, we end up 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.

Let's proceed to step 16:
When dividing 4000 by 520, we get 7 with a remainder of 360.
Use 7 as the next digit of our solution. 
Result so far: 165195.47692307
Deduct 3640 from 4000 and we're left with 360.
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 result is 165195.47692307 with a remainder of 3.6e-07.
