7145142 ÷ 249 
Our goal is to divide 7145142 by 249.

Let's proceed to step 1:
249 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 249

Going ahead to step 2:
249 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 249

Going ahead to step 3:
714 divided by 249 is 2 with a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 498 from 714 to get 216.
Append the next digit (5) from the dividend to 216 and continue with: 2165 / 249

Moving on to step 4:
The number 249 fits into 2165 8 times, leaving a remainder of 173.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 1992 away from 2165, we end up with 173.
Append the next digit (1) from the dividend to 173 and continue with: 1731 / 249

Going ahead to step 5:
If we divide 1731 by 249, we get 6 and a remainder of 237.
Put 6 as the next digit of the answer. 
Result so far: 286.0
If we take 1494 away from 1731, we end up with 237.
Take the next digit (4) from the dividend and append it to 237, then repeat: 2374 / 249

Moving on to step 6:
2374 divided by 249 is 9 with a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 2869.0
If we subtract 2241 from 2374, we get 133.
Append the next digit (2) from the dividend to 133 and continue with: 1332 / 249

Going ahead to step 7:
When dividing 1332 by 249, we get 5 with a remainder of 87.
Record the quotient 5 as the next digit in the result. 
Result so far: 28695.0
If we take 1245 away from 1332, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 8:
249 can be fit into 870 3 times, resulting in a remainder of 123.
Record the quotient 3 as the next digit in the result. 
Result so far: 28695.3
If we subtract 747 from 870, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
249 goes into 1230 4 times with a remainder of 234.
The number 4 becomes the next digit in our result. 
Result so far: 28695.34
Subtracting 996 from 1230 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 10:
249 can be fit into 2340 9 times, resulting in a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 28695.349
Deduct 2241 from 2340 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 11:
The number 249 fits into 990 3 times, leaving a remainder of 243.
Record the quotient 3 as the next digit in the result. 
Result so far: 28695.3493
Subtracting 747 from 990 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Step 12:
When dividing 2430 by 249, we get 9 with a remainder of 189.
Use 9 as the next digit of our solution. 
Result so far: 28695.34939
If we subtract 2241 from 2430, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 13:
The number 249 fits into 1890 7 times, leaving a remainder of 147.
Use 7 as the next digit of our solution. 
Result so far: 28695.349397
Subtracting 1743 from 1890 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 14:
249 goes into 1470 5 times with a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 28695.3493975
If we subtract 1245 from 1470, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 15:
249 goes into 2250 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 28695.34939759
If we subtract 2241 from 2250, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 28695.34939759, with a leftover of 9e-09.
