We look at the division of 66156010 by 925 
We want to figure out the number of times 66156010 can be divided by 925.

Step 1:
The number 925 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 subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 925

On to step 2:
925 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 925

On to step 3:
The number 925 fits into 661 0 times, leaving a remainder of 661.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 661 to get 661.
Include the next digit (5) from the dividend after 661, then repeat: 6615 / 925

Let's proceed to step 4:
925 goes into 6615 7 times with a remainder of 140.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 6475 from 6615, we get 140.
Grab the next digit (6) from the dividend, add it to 140, then carry on: 1406 / 925

Going ahead to step 5:
1406 divided by 925 is 1 with a remainder of 481.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we subtract 925 from 1406, we get 481.
Bring next digit (0) of the dividend behind the 481 and repeat the process: 4810 / 925

Advancing to step 6:
If we divide 4810 by 925, we get 5 and a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 715.0
Deduct 4625 from 4810 and we're left with 185.
Bring next digit (1) of the dividend behind the 185 and repeat the process: 1851 / 925

Step 7:
If we divide 1851 by 925, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 7152.0
Subtracting 1850 from 1851 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 925

Let's proceed to step 8:
The number 925 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 71520.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 925 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 71520.0
Subtracting 0 from 100 leaves us 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.

On to step 10:
The number 925 fits into 1000 1 times, leaving a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 71520.01
Deduct 925 from 1000 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.

On to step 11:
The number 925 fits into 750 0 times, leaving a remainder of 750.
Write down 0 as next digit of the result. 
Result so far: 71520.01
Deduct 0 from 750 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Advancing to step 12:
925 goes into 7500 8 times with a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 71520.0108
Subtract 7400 from 7500 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
When dividing 1000 by 925, we get 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 71520.01081
If we subtract 925 from 1000, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
The number 925 fits into 750 0 times, leaving a remainder of 750.
The next digit of our result is 0. 
Result so far: 71520.01081
The remainder is 750 after subtracting 0 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 15:
925 can be fit into 7500 8 times, resulting in a remainder of 100.
The next digit of our result is 8. 
Result so far: 71520.0108108
Subtracting 7400 from 7500 leaves us 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 16:
The number 925 fits into 1000 1 times, leaving a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 71520.01081081
If we subtract 925 from 1000, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 71520.01081081 and a remainder of 7.5e-08.
