We look at the division of 38691571 by 966 
We're looking to find how many times 966 goes into 38691571.

On to step 1:
The number 966 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 966

Moving on to step 2:
38 divided by 966 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 966

Moving on to step 3:
The number 966 fits into 386 0 times, leaving a remainder of 386.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 386, we get 386.
Include the next digit (9) from the dividend after 386, then repeat: 3869 / 966

Step 4:
The number 966 fits into 3869 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 3864 from 3869 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 966

On to step 5:
966 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 966

On to step 6:
515 divided by 966 is 0 with a remainder of 515.
The next digit of our result is 0. 
Result so far: 400.0
The remainder is 515 after subtracting 0 from 515.
Grab the next digit (7) from the dividend, add it to 515, then carry on: 5157 / 966

On to step 7:
The number 966 fits into 5157 5 times, leaving a remainder of 327.
Record the quotient 5 as the next digit in the result. 
Result so far: 4005.0
Deduct 4830 from 5157 and we're left with 327.
Bring next digit (1) of the dividend behind the 327 and repeat the process: 3271 / 966

Moving on to step 8:
3271 divided by 966 is 3 with a remainder of 373.
The next digit of our result is 3. 
Result so far: 40053.0
The remainder is 373 after subtracting 2898 from 3271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 9:
If we divide 3730 by 966, we get 3 and a remainder of 832.
The next digit of our result is 3. 
Result so far: 40053.3
If we subtract 2898 from 3730, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Going ahead to step 10:
8320 divided by 966 is 8 with a remainder of 592.
The number 8 becomes the next digit in our result. 
Result so far: 40053.38
Subtracting 7728 from 8320 leaves us 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.

On to step 11:
966 goes into 5920 6 times with a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 40053.386
Deduct 5796 from 5920 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 12:
When dividing 1240 by 966, we get 1 with a remainder of 274.
The next digit of our result is 1. 
Result so far: 40053.3861
The remainder is 274 after subtracting 966 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 13:
The number 966 fits into 2740 2 times, leaving a remainder of 808.
Put 2 as the next digit of the answer. 
Result so far: 40053.38612
The remainder is 808 after subtracting 1932 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

On to step 14:
966 can be fit into 8080 8 times, resulting in a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 40053.386128
Subtract 7728 from 8080 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 15:
The number 966 fits into 3520 3 times, leaving a remainder of 622.
The next digit of our result is 3. 
Result so far: 40053.3861283
Subtract 2898 from 3520 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Let's proceed to step 16:
6220 divided by 966 is 6 with a remainder of 424.
The number 6 becomes the next digit in our result. 
Result so far: 40053.38612836
Subtracting 5796 from 6220 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Our division results in 40053.38612836 with a remaining 4.24e-07.
