We divide 51891504 by 249
We want to figure out the number of times 51891504 can be divided by 249.

Moving on to step 1:
The number 249 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 249

Step 2:
If we divide 51 by 249, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 249

On to step 3:
518 divided by 249 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 498 from 518, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 249

On to step 4:
The number 249 fits into 209 0 times, leaving a remainder of 209.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 209 after subtracting 0 from 209.
Fetch the next digit (1) from the dividend, attach it to 209 and continue: 2091 / 249

On to step 5:
249 can be fit into 2091 8 times, resulting in a remainder of 99.
Use 8 as the next digit of our solution. 
Result so far: 208.0
Deduct 1992 from 2091 and we're left with 99.
Grab the next digit (5) from the dividend, add it to 99, then carry on: 995 / 249

Advancing to step 6:
249 can be fit into 995 3 times, resulting in a remainder of 248.
Record the quotient 3 as the next digit in the result. 
Result so far: 2083.0
Subtract 747 from 995 to get 248.
Grab the next digit (0) from the dividend, add it to 248, then carry on: 2480 / 249

Moving on to step 7:
If we divide 2480 by 249, we get 9 and a remainder of 239.
The next digit of our result is 9. 
Result so far: 20839.0
Subtracting 2241 from 2480 leaves us with 239.
Grab the next digit (4) from the dividend, add it to 239, then carry on: 2394 / 249

Step 8:
249 goes into 2394 9 times with a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 208399.0
The remainder is 153 after subtracting 2241 from 2394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 9:
If we divide 1530 by 249, we get 6 and a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 208399.6
The remainder is 36 after subtracting 1494 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
If we divide 360 by 249, we get 1 and a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 208399.61
Deduct 249 from 360 and we're left with 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 11:
249 goes into 1110 4 times with a remainder of 114.
The next digit of our result is 4. 
Result so far: 208399.614
Subtracting 996 from 1110 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 12:
When dividing 1140 by 249, we get 4 with a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 208399.6144
Subtracting 996 from 1140 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 208399.6144, with a leftover of 0.00144.
