We look at the division of 70399253 by 880 
Let's see how many times 880 fits into 70399253.

Step 1:
If we divide 7 by 880, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 880

Moving on to step 2:
70 divided by 880 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 880

Let's proceed to step 3:
When dividing 703 by 880, we get 0 with a remainder of 703.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 703 to get 703.
Bring next digit (9) of the dividend behind the 703 and repeat the process: 7039 / 880

Let's proceed to step 4:
880 goes into 7039 7 times with a remainder of 879.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 6160 from 7039 to get 879.
Grab the next digit (9) from the dividend, add it to 879, then carry on: 8799 / 880

Let's proceed to step 5:
When dividing 8799 by 880, we get 9 with a remainder of 879.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtracting 7920 from 8799 leaves us with 879.
Take the next digit (2) from the dividend and append it to 879, then repeat: 8792 / 880

Let's proceed to step 6:
If we divide 8792 by 880, we get 9 and a remainder of 872.
The number 9 becomes the next digit in our result. 
Result so far: 799.0
Subtract 7920 from 8792 to get 872.
Take the next digit (5) from the dividend and append it to 872, then repeat: 8725 / 880

Let's proceed to step 7:
880 goes into 8725 9 times with a remainder of 805.
Record the quotient 9 as the next digit in the result. 
Result so far: 7999.0
Deduct 7920 from 8725 and we're left with 805.
Bring next digit (3) of the dividend behind the 805 and repeat the process: 8053 / 880

On to step 8:
The number 880 fits into 8053 9 times, leaving a remainder of 133.
The next digit of our result is 9. 
Result so far: 79999.0
Subtract 7920 from 8053 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 9:
880 goes into 1330 1 times with a remainder of 450.
Record the quotient 1 as the next digit in the result. 
Result so far: 79999.1
If we take 880 away from 1330, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 10:
4500 divided by 880 is 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 79999.15
If we subtract 4400 from 4500, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
880 goes into 1000 1 times with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 79999.151
Subtracting 880 from 1000 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
If we divide 1200 by 880, we get 1 and a remainder of 320.
The number 1 becomes the next digit in our result. 
Result so far: 79999.1511
Subtract 880 from 1200 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 79999.1511 with a remainder of 0.0032.
