We look at the division of 13558641 by 961 
We're looking to find how many times 961 goes into 13558641.

Advancing to step 1:
The number 961 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 961

Advancing to step 2:
961 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 961

On to step 3:
If we divide 135 by 961, we get 0 and a remainder of 135.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 135 to get 135.
Grab the next digit (5) from the dividend, add it to 135, then carry on: 1355 / 961

Advancing to step 4:
If we divide 1355 by 961, we get 1 and a remainder of 394.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 961 from 1355 and we're left with 394.
Grab the next digit (8) from the dividend, add it to 394, then carry on: 3948 / 961

Step 5:
961 goes into 3948 4 times with a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 3844 from 3948 and we're left with 104.
Grab the next digit (6) from the dividend, add it to 104, then carry on: 1046 / 961

Going ahead to step 6:
When dividing 1046 by 961, we get 1 with a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 141.0
Subtracting 961 from 1046 leaves us with 85.
Take the next digit (4) from the dividend and append it to 85, then repeat: 854 / 961

Going ahead to step 7:
When dividing 854 by 961, we get 0 with a remainder of 854.
Write down 0 as next digit of the result. 
Result so far: 1410.0
Subtracting 0 from 854 leaves us with 854.
Append the next digit (1) from the dividend to 854 and continue with: 8541 / 961

Let's proceed to step 8:
The number 961 fits into 8541 8 times, leaving a remainder of 853.
The next digit of our result is 8. 
Result so far: 14108.0
The remainder is 853 after subtracting 7688 from 8541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

Step 9:
If we divide 8530 by 961, we get 8 and a remainder of 842.
The number 8 becomes the next digit in our result. 
Result so far: 14108.8
If we take 7688 away from 8530, we end up with 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Going ahead to step 10:
When dividing 8420 by 961, we get 8 with a remainder of 732.
Use 8 as the next digit of our solution. 
Result so far: 14108.88
Subtract 7688 from 8420 to get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

After the division, we end up with 14108.88 and a remainder of 0.732.
