9961064 ÷ 772 
We want to divide 9961064 by 772.

Step 1:
9 divided by 772 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 772

On to step 2:
If we divide 99 by 772, we get 0 and a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (6) from the dividend and append it to 99, then repeat: 996 / 772

Step 3:
If we divide 996 by 772, we get 1 and a remainder of 224.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 772 from 996 and we're left with 224.
Include the next digit (1) from the dividend after 224, then repeat: 2241 / 772

Step 4:
772 can be fit into 2241 2 times, resulting in a remainder of 697.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1544 from 2241, we get 697.
Take the next digit (0) from the dividend and append it to 697, then repeat: 6970 / 772

On to step 5:
The number 772 fits into 6970 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we take 6948 away from 6970, we end up with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 772

Advancing to step 6:
772 goes into 226 0 times with a remainder of 226.
The next digit of our result is 0. 
Result so far: 1290.0
Deduct 0 from 226 and we're left with 226.
Grab the next digit (4) from the dividend, add it to 226, then carry on: 2264 / 772

Going ahead to step 7:
2264 divided by 772 is 2 with a remainder of 720.
Write down 2 as next digit of the result. 
Result so far: 12902.0
If we take 1544 away from 2264, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 8:
7200 divided by 772 is 9 with a remainder of 252.
Put 9 as the next digit of the answer. 
Result so far: 12902.9
Subtract 6948 from 7200 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 9:
772 goes into 2520 3 times with a remainder of 204.
Write down 3 as next digit of the result. 
Result so far: 12902.93
If we take 2316 away from 2520, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 10:
When dividing 2040 by 772, we get 2 with a remainder of 496.
Put 2 as the next digit of the answer. 
Result so far: 12902.932
If we subtract 1544 from 2040, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 11:
772 can be fit into 4960 6 times, resulting in a remainder of 328.
The next digit of our result is 6. 
Result so far: 12902.9326
Subtract 4632 from 4960 to 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.

Let's proceed to step 12:
When dividing 3280 by 772, we get 4 with a remainder of 192.
The next digit of our result is 4. 
Result so far: 12902.93264
If we subtract 3088 from 3280, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 13:
The number 772 fits into 1920 2 times, leaving a remainder of 376.
Put 2 as the next digit of the answer. 
Result so far: 12902.932642
Subtract 1544 from 1920 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 14:
The number 772 fits into 3760 4 times, leaving a remainder of 672.
Record the quotient 4 as the next digit in the result. 
Result so far: 12902.9326424
Subtract 3088 from 3760 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 15:
772 can be fit into 6720 8 times, resulting in a remainder of 544.
The number 8 becomes the next digit in our result. 
Result so far: 12902.93264248
If we subtract 6176 from 6720, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The final outcome is 12902.93264248, with a leftover of 5.44e-07.
