We're dividing 78374803 by 307 
We want to figure out the number of times 78374803 can be divided by 307.

Step 1:
When dividing 7 by 307, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 307

Step 2:
307 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 307

Advancing to step 3:
307 goes into 783 2 times with a remainder of 169.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 614 from 783, we get 169.
Take the next digit (7) from the dividend and append it to 169, then repeat: 1697 / 307

Let's proceed to step 4:
1697 divided by 307 is 5 with a remainder of 162.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 1535 from 1697 to get 162.
Include the next digit (4) from the dividend after 162, then repeat: 1624 / 307

Moving on to step 5:
When dividing 1624 by 307, we get 5 with a remainder of 89.
Put 5 as the next digit of the answer. 
Result so far: 255.0
The remainder is 89 after subtracting 1535 from 1624.
Append the next digit (8) from the dividend to 89 and continue with: 898 / 307

Let's proceed to step 6:
If we divide 898 by 307, we get 2 and a remainder of 284.
The next digit of our result is 2. 
Result so far: 2552.0
Deduct 614 from 898 and we're left with 284.
Include the next digit (0) from the dividend after 284, then repeat: 2840 / 307

Going ahead to step 7:
307 goes into 2840 9 times with a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 25529.0
If we take 2763 away from 2840, we end up with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 307

Going ahead to step 8:
If we divide 773 by 307, we get 2 and a remainder of 159.
Use 2 as the next digit of our solution. 
Result so far: 255292.0
If we take 614 away from 773, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 9:
If we divide 1590 by 307, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 255292.5
If we subtract 1535 from 1590, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
The number 307 fits into 550 1 times, leaving a remainder of 243.
The number 1 becomes the next digit in our result. 
Result so far: 255292.51
Subtract 307 from 550 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 11:
307 can be fit into 2430 7 times, resulting in a remainder of 281.
Write down 7 as next digit of the result. 
Result so far: 255292.517
Deduct 2149 from 2430 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Step 12:
The number 307 fits into 2810 9 times, leaving a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 255292.5179
The remainder is 47 after subtracting 2763 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 13:
The number 307 fits into 470 1 times, leaving a remainder of 163.
The number 1 becomes the next digit in our result. 
Result so far: 255292.51791
If we subtract 307 from 470, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 14:
1630 divided by 307 is 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 255292.517915
If we subtract 1535 from 1630, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 15:
When dividing 950 by 307, we get 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 255292.5179153
If we subtract 921 from 950, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 16:
307 goes into 290 0 times with a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 255292.5179153
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

After the division, we end up with 255292.5179153 and a remainder of 2.9e-07.
