We're dividing 81978873 by 961 
We're looking to find how many times 961 goes into 81978873.

Advancing to step 1:
The number 961 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 961

On to step 2:
961 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 961

Advancing to step 3:
When dividing 819 by 961, we get 0 with a remainder of 819.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 819, we end up with 819.
Take the next digit (7) from the dividend and append it to 819, then repeat: 8197 / 961

Going ahead to step 4:
The number 961 fits into 8197 8 times, leaving a remainder of 509.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 7688 from 8197 leaves us with 509.
Take the next digit (8) from the dividend and append it to 509, then repeat: 5098 / 961

Let's proceed to step 5:
5098 divided by 961 is 5 with a remainder of 293.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Deduct 4805 from 5098 and we're left with 293.
Take the next digit (8) from the dividend and append it to 293, then repeat: 2938 / 961

Let's proceed to step 6:
When dividing 2938 by 961, we get 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 853.0
Subtracting 2883 from 2938 leaves us with 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 961

Step 7:
When dividing 557 by 961, we get 0 with a remainder of 557.
The next digit of our result is 0. 
Result so far: 8530.0
Subtracting 0 from 557 leaves us with 557.
Bring next digit (3) of the dividend behind the 557 and repeat the process: 5573 / 961

Advancing to step 8:
If we divide 5573 by 961, we get 5 and a remainder of 768.
Use 5 as the next digit of our solution. 
Result so far: 85305.0
If we subtract 4805 from 5573, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Step 9:
961 goes into 7680 7 times with a remainder of 953.
The number 7 becomes the next digit in our result. 
Result so far: 85305.7
If we take 6727 away from 7680, we end up with 953.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9530, and continue the process.

Moving on to step 10:
961 can be fit into 9530 9 times, resulting in a remainder of 881.
The number 9 becomes the next digit in our result. 
Result so far: 85305.79
The remainder is 881 after subtracting 8649 from 9530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8810, and continue the process.

Going ahead to step 11:
When dividing 8810 by 961, we get 9 with a remainder of 161.
The next digit of our result is 9. 
Result so far: 85305.799
Subtracting 8649 from 8810 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

The quotient of the division is 85305.799, and the remainder is 0.0161.
