54261146 divided by 961 
We want to figure out the number of times 54261146 can be divided by 961.

Step 1:
The number 961 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 961

Going ahead to step 2:
The number 961 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 961

Advancing to step 3:
The number 961 fits into 542 0 times, leaving a remainder of 542.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 542 and we're left with 542.
Take the next digit (6) from the dividend and append it to 542, then repeat: 5426 / 961

Going ahead to step 4:
5426 divided by 961 is 5 with a remainder of 621.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 4805 from 5426 to get 621.
Bring next digit (1) of the dividend behind the 621 and repeat the process: 6211 / 961

Advancing to step 5:
6211 divided by 961 is 6 with a remainder of 445.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we subtract 5766 from 6211, we get 445.
Take the next digit (1) from the dividend and append it to 445, then repeat: 4451 / 961

Let's proceed to step 6:
If we divide 4451 by 961, we get 4 and a remainder of 607.
The next digit of our result is 4. 
Result so far: 564.0
Subtracting 3844 from 4451 leaves us with 607.
Fetch the next digit (4) from the dividend, attach it to 607 and continue: 6074 / 961

Advancing to step 7:
961 goes into 6074 6 times with a remainder of 308.
The next digit of our result is 6. 
Result so far: 5646.0
The remainder is 308 after subtracting 5766 from 6074.
Fetch the next digit (6) from the dividend, attach it to 308 and continue: 3086 / 961

Going ahead to step 8:
When dividing 3086 by 961, we get 3 with a remainder of 203.
The next digit of our result is 3. 
Result so far: 56463.0
If we take 2883 away from 3086, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 9:
If we divide 2030 by 961, we get 2 and a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 56463.2
Deduct 1922 from 2030 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
961 can be fit into 1080 1 times, resulting in a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 56463.21
If we take 961 away from 1080, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 11:
961 goes into 1190 1 times with a remainder of 229.
Write down 1 as next digit of the result. 
Result so far: 56463.211
Deduct 961 from 1190 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final outcome is 56463.211, with a leftover of 0.0229.
