72900201 ÷ 162 
We want to figure out the number of times 72900201 can be divided by 162.

On to step 1:
162 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 162

Moving on to step 2:
72 divided by 162 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 162

Step 3:
If we divide 729 by 162, we get 4 and a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 648 from 729, we get 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 162

Step 4:
162 can be fit into 810 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 810 from 810 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 162

Step 5:
When dividing 0 by 162, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 450.0
If we subtract 0 from 0, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 162

Step 6:
162 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 4500.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 162

Going ahead to step 7:
If we divide 20 by 162, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 45000.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 162

Step 8:
201 divided by 162 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 450001.0
The remainder is 39 after subtracting 162 from 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
162 goes into 390 2 times with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 450001.2
Deduct 324 from 390 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
If we divide 660 by 162, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 450001.24
Subtract 648 from 660 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 162 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 450001.24
If we take 0 away from 120, we end up 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.

Step 12:
When dividing 1200 by 162, we get 7 with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 450001.2407
Subtract 1134 from 1200 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
The number 162 fits into 660 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 450001.24074
If we take 648 away from 660, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
The number 162 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 450001.24074
If we take 0 away from 120, we end up 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.

Let's proceed to step 15:
162 goes into 1200 7 times with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 450001.2407407
The remainder is 66 after subtracting 1134 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 16:
The number 162 fits into 660 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 450001.24074074
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 450001.24074074 with a remaining 1.2e-08.
