We divide 78429920 by 307
We're looking to find how many times 307 goes into 78429920.

Let's proceed to step 1:
The number 307 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
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 / 307

Step 2:
When dividing 78 by 307, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 307

Step 3:
When dividing 784 by 307, we get 2 with a remainder of 170.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 614 from 784, we get 170.
Grab the next digit (2) from the dividend, add it to 170, then carry on: 1702 / 307

Let's proceed to step 4:
The number 307 fits into 1702 5 times, leaving a remainder of 167.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 1535 away from 1702, we end up with 167.
Bring next digit (9) of the dividend behind the 167 and repeat the process: 1679 / 307

Moving on to step 5:
The number 307 fits into 1679 5 times, leaving a remainder of 144.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
Deduct 1535 from 1679 and we're left with 144.
Grab the next digit (9) from the dividend, add it to 144, then carry on: 1449 / 307

Going ahead to step 6:
307 can be fit into 1449 4 times, resulting in a remainder of 221.
Record the quotient 4 as the next digit in the result. 
Result so far: 2554.0
If we subtract 1228 from 1449, we get 221.
Include the next digit (2) from the dividend after 221, then repeat: 2212 / 307

Moving on to step 7:
When dividing 2212 by 307, we get 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 25547.0
If we subtract 2149 from 2212, we get 63.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 307

Let's proceed to step 8:
When dividing 630 by 307, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 255472.0
Subtracting 614 from 630 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
307 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 255472.0
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
307 can be fit into 1600 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 255472.05
Deduct 1535 from 1600 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
If we divide 650 by 307, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 255472.052
If we take 614 away from 650, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
If we divide 360 by 307, we get 1 and a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 255472.0521
Subtracting 307 from 360 leaves us 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.

Step 13:
307 goes into 530 1 times with a remainder of 223.
The number 1 becomes the next digit in our result. 
Result so far: 255472.05211
If we take 307 away from 530, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

The final outcome is 255472.05211, with a leftover of 0.000223.
