51481963 divided by 397 
Let's see how many times 397 fits into 51481963.

Let's proceed to step 1:
5 divided by 397 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 397

Going ahead to step 2:
397 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 397

On to step 3:
397 can be fit into 514 1 times, resulting in a remainder of 117.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 117 after subtracting 397 from 514.
Bring next digit (8) of the dividend behind the 117 and repeat the process: 1178 / 397

Advancing to step 4:
If we divide 1178 by 397, we get 2 and a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 794 from 1178 to get 384.
Append the next digit (1) from the dividend to 384 and continue with: 3841 / 397

Going ahead to step 5:
397 goes into 3841 9 times with a remainder of 268.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtracting 3573 from 3841 leaves us with 268.
Grab the next digit (9) from the dividend, add it to 268, then carry on: 2689 / 397

Step 6:
2689 divided by 397 is 6 with a remainder of 307.
Write down 6 as next digit of the result. 
Result so far: 1296.0
Subtract 2382 from 2689 to get 307.
Bring next digit (6) of the dividend behind the 307 and repeat the process: 3076 / 397

Moving on to step 7:
397 can be fit into 3076 7 times, resulting in a remainder of 297.
Write down 7 as next digit of the result. 
Result so far: 12967.0
The remainder is 297 after subtracting 2779 from 3076.
Grab the next digit (3) from the dividend, add it to 297, then carry on: 2973 / 397

Advancing to step 8:
2973 divided by 397 is 7 with a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 129677.0
Subtract 2779 from 2973 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 9:
The number 397 fits into 1940 4 times, leaving a remainder of 352.
Record the quotient 4 as the next digit in the result. 
Result so far: 129677.4
The remainder is 352 after subtracting 1588 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 10:
397 can be fit into 3520 8 times, resulting in a remainder of 344.
Use 8 as the next digit of our solution. 
Result so far: 129677.48
If we subtract 3176 from 3520, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 11:
If we divide 3440 by 397, we get 8 and a remainder of 264.
The next digit of our result is 8. 
Result so far: 129677.488
If we subtract 3176 from 3440, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final result is 129677.488 with a remainder of 0.0264.
