53104589 ÷ 963 
We want to divide 53104589 by 963.

Going ahead to step 1:
5 divided by 963 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 963

On to step 2:
963 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 963

On to step 3:
If we divide 531 by 963, we get 0 and a remainder of 531.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 531 after subtracting 0 from 531.
Take the next digit (0) from the dividend and append it to 531, then repeat: 5310 / 963

Advancing to step 4:
5310 divided by 963 is 5 with a remainder of 495.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4815 away from 5310, we end up with 495.
Bring next digit (4) of the dividend behind the 495 and repeat the process: 4954 / 963

Advancing to step 5:
The number 963 fits into 4954 5 times, leaving a remainder of 139.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we subtract 4815 from 4954, we get 139.
Grab the next digit (5) from the dividend, add it to 139, then carry on: 1395 / 963

Advancing to step 6:
If we divide 1395 by 963, we get 1 and a remainder of 432.
The next digit of our result is 1. 
Result so far: 551.0
If we subtract 963 from 1395, we get 432.
Take the next digit (8) from the dividend and append it to 432, then repeat: 4328 / 963

Let's proceed to step 7:
The number 963 fits into 4328 4 times, leaving a remainder of 476.
The number 4 becomes the next digit in our result. 
Result so far: 5514.0
Deduct 3852 from 4328 and we're left with 476.
Bring next digit (9) of the dividend behind the 476 and repeat the process: 4769 / 963

Step 8:
963 goes into 4769 4 times with a remainder of 917.
Put 4 as the next digit of the answer. 
Result so far: 55144.0
Deduct 3852 from 4769 and we're left with 917.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9170, and continue the process.

Advancing to step 9:
The number 963 fits into 9170 9 times, leaving a remainder of 503.
Use 9 as the next digit of our solution. 
Result so far: 55144.9
If we subtract 8667 from 9170, we get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Advancing to step 10:
When dividing 5030 by 963, we get 5 with a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 55144.95
The remainder is 215 after subtracting 4815 from 5030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 11:
2150 divided by 963 is 2 with a remainder of 224.
The next digit of our result is 2. 
Result so far: 55144.952
If we take 1926 away from 2150, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 12:
963 goes into 2240 2 times with a remainder of 314.
The number 2 becomes the next digit in our result. 
Result so far: 55144.9522
The remainder is 314 after subtracting 1926 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

After the division, we end up with 55144.9522 and a remainder of 0.00314.
