42850524 ÷ 249 
We want to figure out the number of times 42850524 can be divided by 249.

Going ahead to step 1:
When dividing 4 by 249, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 249

Let's proceed to step 2:
249 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 249

On to step 3:
If we divide 428 by 249, we get 1 and a remainder of 179.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 249 away from 428, we end up with 179.
Bring next digit (5) of the dividend behind the 179 and repeat the process: 1795 / 249

Let's proceed to step 4:
249 goes into 1795 7 times with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 1743 from 1795, we get 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 249

Going ahead to step 5:
If we divide 520 by 249, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
If we subtract 498 from 520, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 249

Let's proceed to step 6:
When dividing 225 by 249, we get 0 with a remainder of 225.
Write down 0 as next digit of the result. 
Result so far: 1720.0
Deduct 0 from 225 and we're left with 225.
Include the next digit (2) from the dividend after 225, then repeat: 2252 / 249

Advancing to step 7:
249 goes into 2252 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 17209.0
If we take 2241 away from 2252, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 249

Advancing to step 8:
249 goes into 114 0 times with a remainder of 114.
Put 0 as the next digit of the answer. 
Result so far: 172090.0
Deduct 0 from 114 and we're left 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.

Step 9:
The number 249 fits into 1140 4 times, leaving a remainder of 144.
The next digit of our result is 4. 
Result so far: 172090.4
If we take 996 away from 1140, we end up 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.

On to step 10:
If we divide 1440 by 249, we get 5 and a remainder of 195.
The next digit of our result is 5. 
Result so far: 172090.45
If we subtract 1245 from 1440, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 11:
When dividing 1950 by 249, we get 7 with a remainder of 207.
Use 7 as the next digit of our solution. 
Result so far: 172090.457
Deduct 1743 from 1950 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 12:
249 goes into 2070 8 times with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 172090.4578
Subtract 1992 from 2070 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 13:
780 divided by 249 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 172090.45783
If we subtract 747 from 780, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
When dividing 330 by 249, we get 1 with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 172090.457831
Subtracting 249 from 330 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 15:
810 divided by 249 is 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 172090.4578313
The remainder is 63 after subtracting 747 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 16:
249 can be fit into 630 2 times, resulting in a remainder of 132.
Use 2 as the next digit of our solution. 
Result so far: 172090.45783132
If we subtract 498 from 630, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Our division results in 172090.45783132 with a remaining 1.32e-07.
