36990998 ÷ 225 
We want to figure out the number of times 36990998 can be divided by 225.

On to step 1:
When dividing 3 by 225, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 225

Step 2:
36 divided by 225 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 225

Going ahead to step 3:
When dividing 369 by 225, we get 1 with a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 225 from 369 to get 144.
Append the next digit (9) from the dividend to 144 and continue with: 1449 / 225

Going ahead to step 4:
225 can be fit into 1449 6 times, resulting in a remainder of 99.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 1350 from 1449 to get 99.
Append the next digit (0) from the dividend to 99 and continue with: 990 / 225

Moving on to step 5:
When dividing 990 by 225, we get 4 with a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
If we take 900 away from 990, we end up with 90.
Take the next digit (9) from the dividend and append it to 90, then repeat: 909 / 225

Step 6:
The number 225 fits into 909 4 times, leaving a remainder of 9.
The next digit of our result is 4. 
Result so far: 1644.0
If we subtract 900 from 909, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 225

Step 7:
225 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 16440.0
The remainder is 99 after subtracting 0 from 99.
Fetch the next digit (8) from the dividend, attach it to 99 and continue: 998 / 225

Moving on to step 8:
225 can be fit into 998 4 times, resulting in a remainder of 98.
Put 4 as the next digit of the answer. 
Result so far: 164404.0
Deduct 900 from 998 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 9:
If we divide 980 by 225, we get 4 and a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 164404.4
If we take 900 away from 980, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
If we divide 800 by 225, we get 3 and a remainder of 125.
Record the quotient 3 as the next digit in the result. 
Result so far: 164404.43
Subtract 675 from 800 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
When dividing 1250 by 225, we get 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 164404.435
Deduct 1125 from 1250 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
225 goes into 1250 5 times with a remainder of 125.
The next digit of our result is 5. 
Result so far: 164404.4355
Subtract 1125 from 1250 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final result is 164404.4355 with a remainder of 0.00125.
