Let's divide 19809985 by 525
We want to figure out the number of times 19809985 can be divided by 525.

Moving on to step 1:
525 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 525

On to step 2:
When dividing 19 by 525, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 525

Step 3:
198 divided by 525 is 0 with a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 198, we get 198.
Include the next digit (0) from the dividend after 198, then repeat: 1980 / 525

Let's proceed to step 4:
525 can be fit into 1980 3 times, resulting in a remainder of 405.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1575 away from 1980, we end up with 405.
Grab the next digit (9) from the dividend, add it to 405, then carry on: 4059 / 525

Step 5:
If we divide 4059 by 525, we get 7 and a remainder of 384.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 3675 from 4059, we get 384.
Fetch the next digit (9) from the dividend, attach it to 384 and continue: 3849 / 525

Going ahead to step 6:
525 can be fit into 3849 7 times, resulting in a remainder of 174.
The number 7 becomes the next digit in our result. 
Result so far: 377.0
The remainder is 174 after subtracting 3675 from 3849.
Grab the next digit (8) from the dividend, add it to 174, then carry on: 1748 / 525

Moving on to step 7:
If we divide 1748 by 525, we get 3 and a remainder of 173.
Use 3 as the next digit of our solution. 
Result so far: 3773.0
If we take 1575 away from 1748, we end up with 173.
Grab the next digit (5) from the dividend, add it to 173, then carry on: 1735 / 525

Let's proceed to step 8:
525 goes into 1735 3 times with a remainder of 160.
Put 3 as the next digit of the answer. 
Result so far: 37733.0
Subtract 1575 from 1735 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 9:
When dividing 1600 by 525, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 37733.3
If we take 1575 away from 1600, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 525 is 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 37733.3
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
525 goes into 2500 4 times with a remainder of 400.
Write down 4 as next digit of the result. 
Result so far: 37733.304
If we take 2100 away from 2500, 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.

Moving on to step 12:
4000 divided by 525 is 7 with a remainder of 325.
The number 7 becomes the next digit in our result. 
Result so far: 37733.3047
If we subtract 3675 from 4000, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 13:
525 can be fit into 3250 6 times, resulting in a remainder of 100.
The next digit of our result is 6. 
Result so far: 37733.30476
Deduct 3150 from 3250 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
525 can be fit into 1000 1 times, resulting in a remainder of 475.
Write down 1 as next digit of the result. 
Result so far: 37733.304761
If we subtract 525 from 1000, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 15:
4750 divided by 525 is 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 37733.3047619
The remainder is 25 after subtracting 4725 from 4750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 16:
525 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 37733.3047619
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

In conclusion, the division gives 37733.3047619 with a balance of 2.5e-07.
