We look at the division of 27902678 by 70 
We want to divide 27902678 by 70.

Step 1:
The number 70 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 70

Moving on to step 2:
70 can be fit into 27 0 times, resulting in a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 70

On to step 3:
The number 70 fits into 279 3 times, leaving a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 210 from 279 and we're left with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 70

Moving on to step 4:
70 can be fit into 690 9 times, resulting in a remainder of 60.
The next digit of our result is 9. 
Result so far: 39.0
Deduct 630 from 690 and we're left with 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 70

Moving on to step 5:
70 goes into 602 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 398.0
Subtracting 560 from 602 leaves us with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 70

Moving on to step 6:
When dividing 426 by 70, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 3986.0
If we take 420 away from 426, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 70

Advancing to step 7:
When dividing 67 by 70, we get 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 39860.0
If we subtract 0 from 67, we get 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 70

Let's proceed to step 8:
678 divided by 70 is 9 with a remainder of 48.
The next digit of our result is 9. 
Result so far: 398609.0
If we take 630 away from 678, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
The number 70 fits into 480 6 times, leaving a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 398609.6
If we subtract 420 from 480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
The number 70 fits into 600 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 398609.68
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 70, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 398609.685
Subtract 350 from 400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
If we divide 500 by 70, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 398609.6857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 398609.68571
Subtracting 70 from 100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 398609.685714
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 15:
When dividing 200 by 70, we get 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 398609.6857142
If we take 140 away from 200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 16:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 398609.68571428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 398609.68571428, with a leftover of 4e-08.
