70185278 ÷ 259 
We want to divide 70185278 by 259.

On to step 1:
259 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 259

On to step 2:
The number 259 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 259

Moving on to step 3:
701 divided by 259 is 2 with a remainder of 183.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 518 from 701 leaves us with 183.
Take the next digit (8) from the dividend and append it to 183, then repeat: 1838 / 259

Going ahead to step 4:
1838 divided by 259 is 7 with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 1813 away from 1838, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 259

Advancing to step 5:
259 goes into 255 0 times with a remainder of 255.
Write down 0 as next digit of the result. 
Result so far: 270.0
Deduct 0 from 255 and we're left with 255.
Bring next digit (2) of the dividend behind the 255 and repeat the process: 2552 / 259

Step 6:
When dividing 2552 by 259, we get 9 with a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 2709.0
Deduct 2331 from 2552 and we're left with 221.
Grab the next digit (7) from the dividend, add it to 221, then carry on: 2217 / 259

Moving on to step 7:
259 can be fit into 2217 8 times, resulting in a remainder of 145.
The number 8 becomes the next digit in our result. 
Result so far: 27098.0
The remainder is 145 after subtracting 2072 from 2217.
Fetch the next digit (8) from the dividend, attach it to 145 and continue: 1458 / 259

Moving on to step 8:
1458 divided by 259 is 5 with a remainder of 163.
Write down 5 as next digit of the result. 
Result so far: 270985.0
Subtract 1295 from 1458 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 9:
When dividing 1630 by 259, we get 6 with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 270985.6
If we take 1554 away from 1630, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
The number 259 fits into 760 2 times, leaving a remainder of 242.
Put 2 as the next digit of the answer. 
Result so far: 270985.62
Subtract 518 from 760 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 11:
When dividing 2420 by 259, we get 9 with a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 270985.629
The remainder is 89 after subtracting 2331 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 12:
890 divided by 259 is 3 with a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 270985.6293
Subtracting 777 from 890 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 13:
259 can be fit into 1130 4 times, resulting in a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 270985.62934
The remainder is 94 after subtracting 1036 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 14:
259 can be fit into 940 3 times, resulting in a remainder of 163.
The number 3 becomes the next digit in our result. 
Result so far: 270985.629343
Deduct 777 from 940 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 15:
259 goes into 1630 6 times with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 270985.6293436
The remainder is 76 after subtracting 1554 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 16:
The number 259 fits into 760 2 times, leaving a remainder of 242.
Use 2 as the next digit of our solution. 
Result so far: 270985.62934362
If we take 518 away from 760, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final outcome is 270985.62934362, with a leftover of 2.42e-07.
