We look at the division of 81637380 by 961 
We're looking to find how many times 961 goes into 81637380.

Going ahead to step 1:
8 divided by 961 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 961

On to step 2:
The number 961 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 961

On to step 3:
961 can be fit into 816 0 times, resulting in a remainder of 816.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 816 leaves us with 816.
Append the next digit (3) from the dividend to 816 and continue with: 8163 / 961

Moving on to step 4:
961 can be fit into 8163 8 times, resulting in a remainder of 475.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 7688 from 8163, we get 475.
Append the next digit (7) from the dividend to 475 and continue with: 4757 / 961

Step 5:
When dividing 4757 by 961, we get 4 with a remainder of 913.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Deduct 3844 from 4757 and we're left with 913.
Include the next digit (3) from the dividend after 913, then repeat: 9133 / 961

Going ahead to step 6:
961 goes into 9133 9 times with a remainder of 484.
Write down 9 as next digit of the result. 
Result so far: 849.0
If we take 8649 away from 9133, we end up with 484.
Fetch the next digit (8) from the dividend, attach it to 484 and continue: 4848 / 961

Moving on to step 7:
4848 divided by 961 is 5 with a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 8495.0
Deduct 4805 from 4848 and we're left with 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 961

Step 8:
961 can be fit into 430 0 times, resulting in a remainder of 430.
Put 0 as the next digit of the answer. 
Result so far: 84950.0
The remainder is 430 after subtracting 0 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 9:
When dividing 4300 by 961, we get 4 with a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 84950.4
If we take 3844 away from 4300, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 10:
961 can be fit into 4560 4 times, resulting in a remainder of 716.
The next digit of our result is 4. 
Result so far: 84950.44
Deduct 3844 from 4560 and we're left 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.

Our division results in 84950.44 with a remaining 0.716.
