We're dividing 66620391 by 976 
Let's see how many times 976 fits into 66620391.

On to step 1:
6 divided by 976 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 976

Let's proceed to step 2:
66 divided by 976 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 976

Advancing to step 3:
The number 976 fits into 666 0 times, leaving a remainder of 666.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 666 to get 666.
Fetch the next digit (2) from the dividend, attach it to 666 and continue: 6662 / 976

Going ahead to step 4:
976 goes into 6662 6 times with a remainder of 806.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 5856 from 6662 leaves us with 806.
Grab the next digit (0) from the dividend, add it to 806, then carry on: 8060 / 976

Moving on to step 5:
8060 divided by 976 is 8 with a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we take 7808 away from 8060, we end up with 252.
Fetch the next digit (3) from the dividend, attach it to 252 and continue: 2523 / 976

Advancing to step 6:
2523 divided by 976 is 2 with a remainder of 571.
The next digit of our result is 2. 
Result so far: 682.0
If we subtract 1952 from 2523, we get 571.
Grab the next digit (9) from the dividend, add it to 571, then carry on: 5719 / 976

Moving on to step 7:
The number 976 fits into 5719 5 times, leaving a remainder of 839.
Put 5 as the next digit of the answer. 
Result so far: 6825.0
Deduct 4880 from 5719 and we're left with 839.
Grab the next digit (1) from the dividend, add it to 839, then carry on: 8391 / 976

Step 8:
When dividing 8391 by 976, we get 8 with a remainder of 583.
The next digit of our result is 8. 
Result so far: 68258.0
The remainder is 583 after subtracting 7808 from 8391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Advancing to step 9:
976 can be fit into 5830 5 times, resulting in a remainder of 950.
Put 5 as the next digit of the answer. 
Result so far: 68258.5
If we subtract 4880 from 5830, we get 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Step 10:
976 goes into 9500 9 times with a remainder of 716.
The number 9 becomes the next digit in our result. 
Result so far: 68258.59
If we take 8784 away from 9500, we end up with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 11:
If we divide 7160 by 976, we get 7 and a remainder of 328.
Use 7 as the next digit of our solution. 
Result so far: 68258.597
If we subtract 6832 from 7160, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 12:
976 goes into 3280 3 times with a remainder of 352.
Record the quotient 3 as the next digit in the result. 
Result so far: 68258.5973
The remainder is 352 after subtracting 2928 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 13:
976 goes into 3520 3 times with a remainder of 592.
The number 3 becomes the next digit in our result. 
Result so far: 68258.59733
Deduct 2928 from 3520 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

After the division, we end up with 68258.59733 and a remainder of 0.000592.
