We look at the division of 878474 by 69 
We're looking to find how many times 69 goes into 878474.

Step 1:
The number 69 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 69

Step 2:
69 can be fit into 87 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 69 from 87 leaves us with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 69

On to step 3:
When dividing 188 by 69, we get 2 with a remainder of 50.
The next digit of our result is 2. 
Result so far: 12.0
If we take 138 away from 188, we end up with 50.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 69

Step 4:
69 can be fit into 504 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtracting 483 from 504 leaves us with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 69

On to step 5:
When dividing 217 by 69, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 1273.0
If we take 207 away from 217, we end up with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 69

Advancing to step 6:
The number 69 fits into 104 1 times, leaving a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 12731.0
Subtract 69 from 104 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
69 can be fit into 350 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12731.5
Subtracting 345 from 350 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
The number 69 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 12731.5
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
When dividing 500 by 69, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 12731.507
Subtract 483 from 500 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
170 divided by 69 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 12731.5072
If we subtract 138 from 170, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
When dividing 320 by 69, we get 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 12731.50724
If we take 276 away from 320, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
When dividing 440 by 69, we get 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 12731.507246
Deduct 414 from 440 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
When dividing 260 by 69, we get 3 with a remainder of 53.
The next digit of our result is 3. 
Result so far: 12731.5072463
If we take 207 away from 260, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 14:
When dividing 530 by 69, we get 7 with a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 12731.50724637
If we take 483 away from 530, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 12731.50724637, with a leftover of 4.7e-08.
