We're dividing 78224488 by 513 
Let's see how many times 513 fits into 78224488.

Moving on to step 1:
When dividing 7 by 513, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 513

Step 2:
513 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 513

Going ahead to step 3:
782 divided by 513 is 1 with a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 513 from 782 leaves us with 269.
Take the next digit (2) from the dividend and append it to 269, then repeat: 2692 / 513

Let's proceed to step 4:
2692 divided by 513 is 5 with a remainder of 127.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2565 from 2692 and we're left with 127.
Take the next digit (4) from the dividend and append it to 127, then repeat: 1274 / 513

Advancing to step 5:
513 goes into 1274 2 times with a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtract 1026 from 1274 to get 248.
Append the next digit (4) from the dividend to 248 and continue with: 2484 / 513

Step 6:
513 goes into 2484 4 times with a remainder of 432.
The number 4 becomes the next digit in our result. 
Result so far: 1524.0
If we take 2052 away from 2484, we end up with 432.
Grab the next digit (8) from the dividend, add it to 432, then carry on: 4328 / 513

On to step 7:
If we divide 4328 by 513, we get 8 and a remainder of 224.
The next digit of our result is 8. 
Result so far: 15248.0
Subtract 4104 from 4328 to get 224.
Take the next digit (8) from the dividend and append it to 224, then repeat: 2248 / 513

Going ahead to step 8:
If we divide 2248 by 513, we get 4 and a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 152484.0
Subtract 2052 from 2248 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 9:
If we divide 1960 by 513, we get 3 and a remainder of 421.
Put 3 as the next digit of the answer. 
Result so far: 152484.3
If we subtract 1539 from 1960, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Advancing to step 10:
The number 513 fits into 4210 8 times, leaving a remainder of 106.
Put 8 as the next digit of the answer. 
Result so far: 152484.38
Subtracting 4104 from 4210 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 11:
513 can be fit into 1060 2 times, resulting in a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 152484.382
Deduct 1026 from 1060 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
340 divided by 513 is 0 with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 152484.382
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 13:
513 goes into 3400 6 times with a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 152484.38206
Subtracting 3078 from 3400 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 14:
513 can be fit into 3220 6 times, resulting in a remainder of 142.
Use 6 as the next digit of our solution. 
Result so far: 152484.382066
If we take 3078 away from 3220, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final result is 152484.382066 with a remainder of 1.42e-05.
