51885948 ÷ 424 
Let's see how many times 424 fits into 51885948.

Advancing to step 1:
5 divided by 424 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 424

Advancing to step 2:
424 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 424

On to step 3:
424 goes into 518 1 times with a remainder of 94.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 424 from 518 and we're left with 94.
Include the next digit (8) from the dividend after 94, then repeat: 948 / 424

Step 4:
948 divided by 424 is 2 with a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 848 away from 948, we end up with 100.
Grab the next digit (5) from the dividend, add it to 100, then carry on: 1005 / 424

On to step 5:
The number 424 fits into 1005 2 times, leaving a remainder of 157.
The next digit of our result is 2. 
Result so far: 122.0
Subtracting 848 from 1005 leaves us with 157.
Grab the next digit (9) from the dividend, add it to 157, then carry on: 1579 / 424

Step 6:
1579 divided by 424 is 3 with a remainder of 307.
Put 3 as the next digit of the answer. 
Result so far: 1223.0
The remainder is 307 after subtracting 1272 from 1579.
Bring next digit (4) of the dividend behind the 307 and repeat the process: 3074 / 424

Moving on to step 7:
If we divide 3074 by 424, we get 7 and a remainder of 106.
The next digit of our result is 7. 
Result so far: 12237.0
The remainder is 106 after subtracting 2968 from 3074.
Fetch the next digit (8) from the dividend, attach it to 106 and continue: 1068 / 424

On to step 8:
424 goes into 1068 2 times with a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 122372.0
The remainder is 220 after subtracting 848 from 1068.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 9:
The number 424 fits into 2200 5 times, leaving a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 122372.5
The remainder is 80 after subtracting 2120 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
The number 424 fits into 800 1 times, leaving a remainder of 376.
Record the quotient 1 as the next digit in the result. 
Result so far: 122372.51
If we subtract 424 from 800, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 11:
The number 424 fits into 3760 8 times, leaving a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 122372.518
Subtract 3392 from 3760 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 12:
3680 divided by 424 is 8 with a remainder of 288.
The next digit of our result is 8. 
Result so far: 122372.5188
The remainder is 288 after subtracting 3392 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 122372.5188, with a leftover of 0.00288.
