12879422 ÷ 961 
Let's see how many times 961 fits into 12879422.

Advancing to step 1:
If we divide 1 by 961, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 961

Step 2:
The number 961 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 961

Step 3:
128 divided by 961 is 0 with a remainder of 128.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Include the next digit (7) from the dividend after 128, then repeat: 1287 / 961

Step 4:
If we divide 1287 by 961, we get 1 and a remainder of 326.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 961 from 1287 and we're left with 326.
Include the next digit (9) from the dividend after 326, then repeat: 3269 / 961

Step 5:
3269 divided by 961 is 3 with a remainder of 386.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 2883 from 3269 leaves us with 386.
Fetch the next digit (4) from the dividend, attach it to 386 and continue: 3864 / 961

Let's proceed to step 6:
961 goes into 3864 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
If we subtract 3844 from 3864, we get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 961

Step 7:
961 goes into 202 0 times with a remainder of 202.
Write down 0 as next digit of the result. 
Result so far: 1340.0
If we subtract 0 from 202, we get 202.
Include the next digit (2) from the dividend after 202, then repeat: 2022 / 961

Going ahead to step 8:
If we divide 2022 by 961, we get 2 and a remainder of 100.
The next digit of our result is 2. 
Result so far: 13402.0
Subtract 1922 from 2022 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 9:
1000 divided by 961 is 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 13402.1
Deduct 961 from 1000 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 10:
If we divide 390 by 961, we get 0 and a remainder of 390.
The next digit of our result is 0. 
Result so far: 13402.1
Subtract 0 from 390 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 11:
961 can be fit into 3900 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 13402.104
The remainder is 56 after subtracting 3844 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
The number 961 fits into 560 0 times, leaving a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 13402.104
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 13:
961 can be fit into 5600 5 times, resulting in a remainder of 795.
Write down 5 as next digit of the result. 
Result so far: 13402.10405
Deduct 4805 from 5600 and we're left with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

On to step 14:
When dividing 7950 by 961, we get 8 with a remainder of 262.
Write down 8 as next digit of the result. 
Result so far: 13402.104058
The remainder is 262 after subtracting 7688 from 7950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 15:
The number 961 fits into 2620 2 times, leaving a remainder of 698.
The number 2 becomes the next digit in our result. 
Result so far: 13402.1040582
If we take 1922 away from 2620, we end up with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

On to step 16:
961 can be fit into 6980 7 times, resulting in a remainder of 253.
Put 7 as the next digit of the answer. 
Result so far: 13402.10405827
If we take 6727 away from 6980, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

The final result is 13402.10405827 with a remainder of 2.53e-07.
