73490011 divided by 525 
We want to figure out the number of times 73490011 can be divided by 525.

Going ahead to step 1:
7 divided by 525 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 525

Moving on to step 2:
525 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 525

On to step 3:
525 can be fit into 734 1 times, resulting in a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 525 from 734 to get 209.
Bring next digit (9) of the dividend behind the 209 and repeat the process: 2099 / 525

On to step 4:
If we divide 2099 by 525, we get 3 and a remainder of 524.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1575 from 2099, we get 524.
Fetch the next digit (0) from the dividend, attach it to 524 and continue: 5240 / 525

Going ahead to step 5:
The number 525 fits into 5240 9 times, leaving a remainder of 515.
Put 9 as the next digit of the answer. 
Result so far: 139.0
If we take 4725 away from 5240, we end up with 515.
Fetch the next digit (0) from the dividend, attach it to 515 and continue: 5150 / 525

Let's proceed to step 6:
If we divide 5150 by 525, we get 9 and a remainder of 425.
The number 9 becomes the next digit in our result. 
Result so far: 1399.0
If we take 4725 away from 5150, we end up with 425.
Grab the next digit (1) from the dividend, add it to 425, then carry on: 4251 / 525

Advancing to step 7:
525 can be fit into 4251 8 times, resulting in a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 13998.0
Subtract 4200 from 4251 to get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 525

Let's proceed to step 8:
If we divide 511 by 525, we get 0 and a remainder of 511.
Use 0 as the next digit of our solution. 
Result so far: 139980.0
Subtracting 0 from 511 leaves us with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 9:
The number 525 fits into 5110 9 times, leaving a remainder of 385.
Put 9 as the next digit of the answer. 
Result so far: 139980.9
If we take 4725 away from 5110, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 10:
525 can be fit into 3850 7 times, resulting in a remainder of 175.
The next digit of our result is 7. 
Result so far: 139980.97
If we subtract 3675 from 3850, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 11:
The number 525 fits into 1750 3 times, leaving a remainder of 175.
Record the quotient 3 as the next digit in the result. 
Result so far: 139980.973
Subtract 1575 from 1750 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 12:
When dividing 1750 by 525, we get 3 with a remainder of 175.
The next digit of our result is 3. 
Result so far: 139980.9733
If we subtract 1575 from 1750, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Our division results in 139980.9733 with a remaining 0.00175.
