70018487 ÷ 251 
We want to figure out the number of times 70018487 can be divided by 251.

Moving on to step 1:
If we divide 7 by 251, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 251

On to step 2:
When dividing 70 by 251, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 251

Let's proceed to step 3:
251 can be fit into 700 2 times, resulting in a remainder of 198.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 502 from 700 and we're left with 198.
Append the next digit (1) from the dividend to 198 and continue with: 1981 / 251

Going ahead to step 4:
1981 divided by 251 is 7 with a remainder of 224.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 1757 from 1981 and we're left with 224.
Fetch the next digit (8) from the dividend, attach it to 224 and continue: 2248 / 251

Going ahead to step 5:
If we divide 2248 by 251, we get 8 and a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 278.0
Subtract 2008 from 2248 to get 240.
Bring next digit (4) of the dividend behind the 240 and repeat the process: 2404 / 251

Step 6:
251 can be fit into 2404 9 times, resulting in a remainder of 145.
Put 9 as the next digit of the answer. 
Result so far: 2789.0
Deduct 2259 from 2404 and we're left with 145.
Take the next digit (8) from the dividend and append it to 145, then repeat: 1458 / 251

Moving on to step 7:
251 goes into 1458 5 times with a remainder of 203.
Record the quotient 5 as the next digit in the result. 
Result so far: 27895.0
Subtracting 1255 from 1458 leaves us with 203.
Include the next digit (7) from the dividend after 203, then repeat: 2037 / 251

Step 8:
251 can be fit into 2037 8 times, resulting in a remainder of 29.
The next digit of our result is 8. 
Result so far: 278958.0
If we take 2008 away from 2037, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
The number 251 fits into 290 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 278958.1
Deduct 251 from 290 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
390 divided by 251 is 1 with a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 278958.11
Subtract 251 from 390 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

In conclusion, the division gives 278958.11 with a balance of 0.139.
