We're dividing 66089875 by 124 
Let's see how many times 124 fits into 66089875.

Going ahead to step 1:
If we divide 6 by 124, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 124

Moving on to step 2:
124 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 (0) from the dividend to 66 and continue with: 660 / 124

On to step 3:
If we divide 660 by 124, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 40 after subtracting 620 from 660.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 124

Advancing to step 4:
124 goes into 408 3 times with a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we subtract 372 from 408, we get 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 124

Advancing to step 5:
If we divide 369 by 124, we get 2 and a remainder of 121.
The next digit of our result is 2. 
Result so far: 532.0
If we subtract 248 from 369, we get 121.
Grab the next digit (8) from the dividend, add it to 121, then carry on: 1218 / 124

Step 6:
If we divide 1218 by 124, we get 9 and a remainder of 102.
Use 9 as the next digit of our solution. 
Result so far: 5329.0
If we subtract 1116 from 1218, we get 102.
Bring next digit (7) of the dividend behind the 102 and repeat the process: 1027 / 124

Going ahead to step 7:
When dividing 1027 by 124, we get 8 with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 53298.0
If we subtract 992 from 1027, we get 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 124

Advancing to step 8:
124 can be fit into 355 2 times, resulting in a remainder of 107.
The number 2 becomes the next digit in our result. 
Result so far: 532982.0
If we take 248 away from 355, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 9:
124 can be fit into 1070 8 times, resulting in a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 532982.8
If we subtract 992 from 1070, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 10:
124 goes into 780 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 532982.86
If we subtract 744 from 780, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
124 goes into 360 2 times with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 532982.862
If we take 248 away from 360, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
1120 divided by 124 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 532982.8629
If we take 1116 away from 1120, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
40 divided by 124 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 532982.8629
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
400 divided by 124 is 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 532982.862903
Deduct 372 from 400 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
124 can be fit into 280 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 532982.8629032
Deduct 248 from 280 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 16:
320 divided by 124 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 532982.86290322
Deduct 248 from 320 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 532982.86290322 with a remainder of 7.2e-08.
