We look at the division of 45200749 by 520 
We want to figure out the number of times 45200749 can be divided by 520.

On to step 1:
When dividing 4 by 520, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 520

On to step 2:
The number 520 fits into 45 0 times, leaving a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 520

Moving on to step 3:
520 can be fit into 452 0 times, resulting in a remainder of 452.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 452 and we're left with 452.
Bring next digit (0) of the dividend behind the 452 and repeat the process: 4520 / 520

Going ahead to step 4:
When dividing 4520 by 520, we get 8 with a remainder of 360.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 4160 from 4520 to get 360.
Grab the next digit (0) from the dividend, add it to 360, then carry on: 3600 / 520

Advancing to step 5:
520 goes into 3600 6 times with a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Deduct 3120 from 3600 and we're left with 480.
Include the next digit (7) from the dividend after 480, then repeat: 4807 / 520

Let's proceed to step 6:
When dividing 4807 by 520, we get 9 with a remainder of 127.
The next digit of our result is 9. 
Result so far: 869.0
If we subtract 4680 from 4807, we get 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 520

Step 7:
520 can be fit into 1274 2 times, resulting in a remainder of 234.
The number 2 becomes the next digit in our result. 
Result so far: 8692.0
The remainder is 234 after subtracting 1040 from 1274.
Grab the next digit (9) from the dividend, add it to 234, then carry on: 2349 / 520

On to step 8:
When dividing 2349 by 520, we get 4 with a remainder of 269.
Use 4 as the next digit of our solution. 
Result so far: 86924.0
Subtract 2080 from 2349 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 9:
The number 520 fits into 2690 5 times, leaving a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 86924.5
The remainder is 90 after subtracting 2600 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
The number 520 fits into 900 1 times, leaving a remainder of 380.
The next digit of our result is 1. 
Result so far: 86924.51
Deduct 520 from 900 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
The number 520 fits into 3800 7 times, leaving a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 86924.517
If we take 3640 away from 3800, 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.

Going ahead to step 12:
520 can be fit into 1600 3 times, resulting in a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 86924.5173
Deduct 1560 from 1600 and we're left 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.

Let's proceed to step 13:
When dividing 400 by 520, we get 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 86924.5173
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.

Moving on to step 14:
If we divide 4000 by 520, we get 7 and a remainder of 360.
Record the quotient 7 as the next digit in the result. 
Result so far: 86924.517307
If we take 3640 away from 4000, we end up 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 15:
When dividing 3600 by 520, we get 6 with a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 86924.5173076
If we take 3120 away from 3600, we end up 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.

Let's proceed to step 16:
When dividing 4800 by 520, we get 9 with a remainder of 120.
The next digit of our result is 9. 
Result so far: 86924.51730769
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.

The final result is 86924.51730769 with a remainder of 1.2e-07.
