69453486 ÷ 878 
We want to divide 69453486 by 878.

Advancing to step 1:
The number 878 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 878

Moving on to step 2:
69 divided by 878 is 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 878

Moving on to step 3:
The number 878 fits into 694 0 times, leaving a remainder of 694.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 694 and we're left with 694.
Bring next digit (5) of the dividend behind the 694 and repeat the process: 6945 / 878

On to step 4:
The number 878 fits into 6945 7 times, leaving a remainder of 799.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 799 after subtracting 6146 from 6945.
Grab the next digit (3) from the dividend, add it to 799, then carry on: 7993 / 878

Going ahead to step 5:
If we divide 7993 by 878, we get 9 and a remainder of 91.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we subtract 7902 from 7993, we get 91.
Fetch the next digit (4) from the dividend, attach it to 91 and continue: 914 / 878

On to step 6:
878 can be fit into 914 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 791.0
If we take 878 away from 914, we end up with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 878

Advancing to step 7:
878 goes into 368 0 times with a remainder of 368.
Write down 0 as next digit of the result. 
Result so far: 7910.0
If we subtract 0 from 368, we get 368.
Fetch the next digit (6) from the dividend, attach it to 368 and continue: 3686 / 878

Moving on to step 8:
3686 divided by 878 is 4 with a remainder of 174.
Use 4 as the next digit of our solution. 
Result so far: 79104.0
If we subtract 3512 from 3686, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 9:
If we divide 1740 by 878, we get 1 and a remainder of 862.
Record the quotient 1 as the next digit in the result. 
Result so far: 79104.1
If we take 878 away from 1740, we end up with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

Going ahead to step 10:
The number 878 fits into 8620 9 times, leaving a remainder of 718.
The number 9 becomes the next digit in our result. 
Result so far: 79104.19
The remainder is 718 after subtracting 7902 from 8620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Moving on to step 11:
The number 878 fits into 7180 8 times, leaving a remainder of 156.
The next digit of our result is 8. 
Result so far: 79104.198
The remainder is 156 after subtracting 7024 from 7180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 12:
If we divide 1560 by 878, we get 1 and a remainder of 682.
The number 1 becomes the next digit in our result. 
Result so far: 79104.1981
The remainder is 682 after subtracting 878 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

On to step 13:
6820 divided by 878 is 7 with a remainder of 674.
Use 7 as the next digit of our solution. 
Result so far: 79104.19817
The remainder is 674 after subtracting 6146 from 6820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Moving on to step 14:
When dividing 6740 by 878, we get 7 with a remainder of 594.
The next digit of our result is 7. 
Result so far: 79104.198177
Subtract 6146 from 6740 to get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

The final outcome is 79104.198177, with a leftover of 5.94e-05.
