68172096 ÷ 525 
We want to figure out the number of times 68172096 can be divided by 525.

Step 1:
The number 525 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 525

Let's proceed to step 2:
525 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 525

Going ahead to step 3:
When dividing 681 by 525, we get 1 with a remainder of 156.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 525 from 681, we get 156.
Take the next digit (7) from the dividend and append it to 156, then repeat: 1567 / 525

Going ahead to step 4:
1567 divided by 525 is 2 with a remainder of 517.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1050 from 1567 to get 517.
Grab the next digit (2) from the dividend, add it to 517, then carry on: 5172 / 525

On to step 5:
5172 divided by 525 is 9 with a remainder of 447.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we take 4725 away from 5172, we end up with 447.
Append the next digit (0) from the dividend to 447 and continue with: 4470 / 525

Moving on to step 6:
4470 divided by 525 is 8 with a remainder of 270.
Record the quotient 8 as the next digit in the result. 
Result so far: 1298.0
Subtract 4200 from 4470 to get 270.
Append the next digit (9) from the dividend to 270 and continue with: 2709 / 525

On to step 7:
When dividing 2709 by 525, we get 5 with a remainder of 84.
Write down 5 as next digit of the result. 
Result so far: 12985.0
Deduct 2625 from 2709 and we're left with 84.
Take the next digit (6) from the dividend and append it to 84, then repeat: 846 / 525

Let's proceed to step 8:
846 divided by 525 is 1 with a remainder of 321.
The number 1 becomes the next digit in our result. 
Result so far: 129851.0
If we take 525 away from 846, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 9:
525 can be fit into 3210 6 times, resulting in a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 129851.6
Subtracting 3150 from 3210 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 525, we get 1 and a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 129851.61
Deduct 525 from 600 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
525 goes into 750 1 times with a remainder of 225.
Put 1 as the next digit of the answer. 
Result so far: 129851.611
Deduct 525 from 750 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

After the division, we end up with 129851.611 and a remainder of 0.0225.
