We're dividing 166125 by 63 
We're looking to find how many times 63 goes into 166125.

Going ahead to step 1:
When dividing 1 by 63, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 63

Going ahead to step 2:
63 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 63

On to step 3:
166 divided by 63 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 126 from 166, we get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 63

Advancing to step 4:
When dividing 401 by 63, we get 6 with a remainder of 23.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 23 after subtracting 378 from 401.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 63

On to step 5:
When dividing 232 by 63, we get 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 263.0
Subtract 189 from 232 to get 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 63

On to step 6:
435 divided by 63 is 6 with a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 2636.0
If we take 378 away from 435, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
570 divided by 63 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 2636.9
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
63 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2636.9
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
63 goes into 300 4 times with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 2636.904
If we take 252 away from 300, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
63 can be fit into 480 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 2636.9047
Deduct 441 from 480 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 11:
63 can be fit into 390 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 2636.90476
Subtracting 378 from 390 leaves us 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.

Advancing to step 12:
The number 63 fits into 120 1 times, leaving a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 2636.904761
If we take 63 away from 120, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 13:
The number 63 fits into 570 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 2636.9047619
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
63 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2636.9047619
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 2636.9047619, with a leftover of 3e-08.
