61307166 ÷ 225 
We want to figure out the number of times 61307166 can be divided by 225.

Going ahead to step 1:
225 goes into 6 0 times with 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.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 225

Going ahead to step 2:
61 divided by 225 is 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Bring next digit (3) of the dividend behind the 61 and repeat the process: 613 / 225

Let's proceed to step 3:
613 divided by 225 is 2 with a remainder of 163.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 450 away from 613, we end up with 163.
Bring next digit (0) of the dividend behind the 163 and repeat the process: 1630 / 225

Going ahead to step 4:
1630 divided by 225 is 7 with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 1575 from 1630, we get 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 225

Moving on to step 5:
225 can be fit into 557 2 times, resulting in a remainder of 107.
Put 2 as the next digit of the answer. 
Result so far: 272.0
Deduct 450 from 557 and we're left with 107.
Take the next digit (1) from the dividend and append it to 107, then repeat: 1071 / 225

On to step 6:
225 can be fit into 1071 4 times, resulting in a remainder of 171.
The number 4 becomes the next digit in our result. 
Result so far: 2724.0
Subtracting 900 from 1071 leaves us with 171.
Fetch the next digit (6) from the dividend, attach it to 171 and continue: 1716 / 225

Let's proceed to step 7:
1716 divided by 225 is 7 with a remainder of 141.
Use 7 as the next digit of our solution. 
Result so far: 27247.0
Subtracting 1575 from 1716 leaves us with 141.
Bring next digit (6) of the dividend behind the 141 and repeat the process: 1416 / 225

Advancing to step 8:
225 goes into 1416 6 times with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 272476.0
If we subtract 1350 from 1416, we 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.

Step 9:
660 divided by 225 is 2 with a remainder of 210.
Record the quotient 2 as the next digit in the result. 
Result so far: 272476.2
Subtracting 450 from 660 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
When dividing 2100 by 225, we get 9 with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 272476.29
If we subtract 2025 from 2100, 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.

On to step 11:
The number 225 fits into 750 3 times, leaving a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 272476.293
If we subtract 675 from 750, 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.

Advancing to step 12:
225 can be fit into 750 3 times, resulting in a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 272476.2933
The remainder is 75 after subtracting 675 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 272476.2933, with a leftover of 0.00075.
