We're dividing 78478951 by 418 
Let's see how many times 418 fits into 78478951.

Going ahead to step 1:
The number 418 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 418

Step 2:
The number 418 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 418

Moving on to step 3:
If we divide 784 by 418, we get 1 and a remainder of 366.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 418 from 784 leaves us with 366.
Grab the next digit (7) from the dividend, add it to 366, then carry on: 3667 / 418

Advancing to step 4:
If we divide 3667 by 418, we get 8 and a remainder of 323.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 3344 from 3667 and we're left with 323.
Append the next digit (8) from the dividend to 323 and continue with: 3238 / 418

Let's proceed to step 5:
418 goes into 3238 7 times with a remainder of 312.
Put 7 as the next digit of the answer. 
Result so far: 187.0
If we subtract 2926 from 3238, we get 312.
Grab the next digit (9) from the dividend, add it to 312, then carry on: 3129 / 418

Going ahead to step 6:
418 goes into 3129 7 times with a remainder of 203.
Use 7 as the next digit of our solution. 
Result so far: 1877.0
Deduct 2926 from 3129 and we're left with 203.
Grab the next digit (5) from the dividend, add it to 203, then carry on: 2035 / 418

Let's proceed to step 7:
418 goes into 2035 4 times with a remainder of 363.
Use 4 as the next digit of our solution. 
Result so far: 18774.0
Deduct 1672 from 2035 and we're left with 363.
Append the next digit (1) from the dividend to 363 and continue with: 3631 / 418

Moving on to step 8:
418 goes into 3631 8 times with a remainder of 287.
Put 8 as the next digit of the answer. 
Result so far: 187748.0
Subtract 3344 from 3631 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 9:
418 can be fit into 2870 6 times, resulting in a remainder of 362.
Write down 6 as next digit of the result. 
Result so far: 187748.6
Deduct 2508 from 2870 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 10:
3620 divided by 418 is 8 with a remainder of 276.
Write down 8 as next digit of the result. 
Result so far: 187748.68
Deduct 3344 from 3620 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 11:
When dividing 2760 by 418, we get 6 with a remainder of 252.
The next digit of our result is 6. 
Result so far: 187748.686
If we subtract 2508 from 2760, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 12:
2520 divided by 418 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 187748.6866
Subtract 2508 from 2520 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 187748.6866, and the remainder is 0.00012.
