We look at the division of 51554878 by 961 
Let's see how many times 961 fits into 51554878.

Step 1:
5 divided by 961 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 961

Moving on to step 2:
When dividing 51 by 961, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 961

Step 3:
When dividing 515 by 961, we get 0 with a remainder of 515.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 515, we get 515.
Grab the next digit (5) from the dividend, add it to 515, then carry on: 5155 / 961

Advancing to step 4:
961 can be fit into 5155 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 4805 from 5155 to get 350.
Fetch the next digit (4) from the dividend, attach it to 350 and continue: 3504 / 961

On to step 5:
961 can be fit into 3504 3 times, resulting in a remainder of 621.
The next digit of our result is 3. 
Result so far: 53.0
Subtracting 2883 from 3504 leaves us with 621.
Append the next digit (8) from the dividend to 621 and continue with: 6218 / 961

On to step 6:
961 goes into 6218 6 times with a remainder of 452.
The number 6 becomes the next digit in our result. 
Result so far: 536.0
Subtracting 5766 from 6218 leaves us with 452.
Fetch the next digit (7) from the dividend, attach it to 452 and continue: 4527 / 961

Let's proceed to step 7:
If we divide 4527 by 961, we get 4 and a remainder of 683.
Put 4 as the next digit of the answer. 
Result so far: 5364.0
If we take 3844 away from 4527, we end up with 683.
Bring next digit (8) of the dividend behind the 683 and repeat the process: 6838 / 961

Going ahead to step 8:
When dividing 6838 by 961, we get 7 with a remainder of 111.
Record the quotient 7 as the next digit in the result. 
Result so far: 53647.0
If we subtract 6727 from 6838, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 9:
961 can be fit into 1110 1 times, resulting in a remainder of 149.
The next digit of our result is 1. 
Result so far: 53647.1
Subtracting 961 from 1110 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 10:
When dividing 1490 by 961, we get 1 with a remainder of 529.
The number 1 becomes the next digit in our result. 
Result so far: 53647.11
Subtract 961 from 1490 to get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

The final result is 53647.11 with a remainder of 0.529.
