78388014 ÷ 609 
We want to divide 78388014 by 609.

Step 1:
If we divide 7 by 609, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 609

Step 2:
78 divided by 609 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 609

Going ahead to step 3:
If we divide 783 by 609, we get 1 and a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 609 from 783, we get 174.
Take the next digit (8) from the dividend and append it to 174, then repeat: 1748 / 609

Advancing to step 4:
609 can be fit into 1748 2 times, resulting in a remainder of 530.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 1218 away from 1748, we end up with 530.
Fetch the next digit (8) from the dividend, attach it to 530 and continue: 5308 / 609

Going ahead to step 5:
If we divide 5308 by 609, we get 8 and a remainder of 436.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtract 4872 from 5308 to get 436.
Grab the next digit (0) from the dividend, add it to 436, then carry on: 4360 / 609

On to step 6:
4360 divided by 609 is 7 with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 1287.0
If we subtract 4263 from 4360, we get 97.
Fetch the next digit (1) from the dividend, attach it to 97 and continue: 971 / 609

Let's proceed to step 7:
609 goes into 971 1 times with a remainder of 362.
Use 1 as the next digit of our solution. 
Result so far: 12871.0
Subtract 609 from 971 to get 362.
Take the next digit (4) from the dividend and append it to 362, then repeat: 3624 / 609

Step 8:
When dividing 3624 by 609, we get 5 with a remainder of 579.
The number 5 becomes the next digit in our result. 
Result so far: 128715.0
Subtract 3045 from 3624 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Advancing to step 9:
609 can be fit into 5790 9 times, resulting in a remainder of 309.
Record the quotient 9 as the next digit in the result. 
Result so far: 128715.9
Deduct 5481 from 5790 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 10:
3090 divided by 609 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 128715.95
If we subtract 3045 from 3090, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
609 goes into 450 0 times with a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 128715.95
Subtracting 0 from 450 leaves us 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.

Moving on to step 12:
The number 609 fits into 4500 7 times, leaving a remainder of 237.
Write down 7 as next digit of the result. 
Result so far: 128715.9507
Subtract 4263 from 4500 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 13:
2370 divided by 609 is 3 with a remainder of 543.
Write down 3 as next digit of the result. 
Result so far: 128715.95073
The remainder is 543 after subtracting 1827 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 14:
When dividing 5430 by 609, we get 8 with a remainder of 558.
Use 8 as the next digit of our solution. 
Result so far: 128715.950738
Subtract 4872 from 5430 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 15:
609 can be fit into 5580 9 times, resulting in a remainder of 99.
Use 9 as the next digit of our solution. 
Result so far: 128715.9507389
The remainder is 99 after subtracting 5481 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 16:
609 can be fit into 990 1 times, resulting in a remainder of 381.
The next digit of our result is 1. 
Result so far: 128715.95073891
Deduct 609 from 990 and we're left with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

The quotient of the division is 128715.95073891, and the remainder is 3.81e-07.
