21777538 ÷ 961 
We want to divide 21777538 by 961.

Going ahead to step 1:
961 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 961

On to step 2:
21 divided by 961 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 961

Let's proceed to step 3:
If we divide 217 by 961, we get 0 and a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 217 leaves us with 217.
Take the next digit (7) from the dividend and append it to 217, then repeat: 2177 / 961

Let's proceed to step 4:
961 goes into 2177 2 times with a remainder of 255.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1922 from 2177, we get 255.
Append the next digit (7) from the dividend to 255 and continue with: 2557 / 961

Advancing to step 5:
If we divide 2557 by 961, we get 2 and a remainder of 635.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 1922 from 2557, we get 635.
Append the next digit (5) from the dividend to 635 and continue with: 6355 / 961

Step 6:
The number 961 fits into 6355 6 times, leaving a remainder of 589.
Write down 6 as next digit of the result. 
Result so far: 226.0
Deduct 5766 from 6355 and we're left with 589.
Include the next digit (3) from the dividend after 589, then repeat: 5893 / 961

Going ahead to step 7:
961 can be fit into 5893 6 times, resulting in a remainder of 127.
Write down 6 as next digit of the result. 
Result so far: 2266.0
If we take 5766 away from 5893, we end up with 127.
Take the next digit (8) from the dividend and append it to 127, then repeat: 1278 / 961

Step 8:
When dividing 1278 by 961, we get 1 with a remainder of 317.
Put 1 as the next digit of the answer. 
Result so far: 22661.0
If we take 961 away from 1278, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 9:
When dividing 3170 by 961, we get 3 with a remainder of 287.
The next digit of our result is 3. 
Result so far: 22661.3
Deduct 2883 from 3170 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Step 10:
961 can be fit into 2870 2 times, resulting in a remainder of 948.
Record the quotient 2 as the next digit in the result. 
Result so far: 22661.32
If we subtract 1922 from 2870, we get 948.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9480, and continue the process.

Advancing to step 11:
9480 divided by 961 is 9 with a remainder of 831.
Use 9 as the next digit of our solution. 
Result so far: 22661.329
Subtracting 8649 from 9480 leaves us with 831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8310, and continue the process.

Let's proceed to step 12:
The number 961 fits into 8310 8 times, leaving a remainder of 622.
Write down 8 as next digit of the result. 
Result so far: 22661.3298
Subtracting 7688 from 8310 leaves us with 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 13:
If we divide 6220 by 961, we get 6 and a remainder of 454.
Use 6 as the next digit of our solution. 
Result so far: 22661.32986
If we take 5766 away from 6220, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 14:
When dividing 4540 by 961, we get 4 with a remainder of 696.
The next digit of our result is 4. 
Result so far: 22661.329864
If we subtract 3844 from 4540, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 15:
The number 961 fits into 6960 7 times, leaving a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 22661.3298647
If we subtract 6727 from 6960, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 16:
961 can be fit into 2330 2 times, resulting in a remainder of 408.
The number 2 becomes the next digit in our result. 
Result so far: 22661.32986472
If we subtract 1922 from 2330, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

In conclusion, the division gives 22661.32986472 with a balance of 4.08e-07.
