Let's divide 78425470 by 807
We're looking to find how many times 807 goes into 78425470.

Step 1:
The number 807 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 807

Let's proceed to step 2:
The number 807 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 807

On to step 3:
784 divided by 807 is 0 with a remainder of 784.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 784 and we're left with 784.
Fetch the next digit (2) from the dividend, attach it to 784 and continue: 7842 / 807

On to step 4:
When dividing 7842 by 807, we get 9 with a remainder of 579.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7263 from 7842, we get 579.
Bring next digit (5) of the dividend behind the 579 and repeat the process: 5795 / 807

Step 5:
5795 divided by 807 is 7 with a remainder of 146.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 5649 from 5795 to get 146.
Bring next digit (4) of the dividend behind the 146 and repeat the process: 1464 / 807

Step 6:
807 can be fit into 1464 1 times, resulting in a remainder of 657.
The number 1 becomes the next digit in our result. 
Result so far: 971.0
Deduct 807 from 1464 and we're left with 657.
Include the next digit (7) from the dividend after 657, then repeat: 6577 / 807

Step 7:
807 can be fit into 6577 8 times, resulting in a remainder of 121.
Put 8 as the next digit of the answer. 
Result so far: 9718.0
Subtracting 6456 from 6577 leaves us with 121.
Append the next digit (0) from the dividend to 121 and continue with: 1210 / 807

On to step 8:
When dividing 1210 by 807, we get 1 with a remainder of 403.
The next digit of our result is 1. 
Result so far: 97181.0
The remainder is 403 after subtracting 807 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Step 9:
4030 divided by 807 is 4 with a remainder of 802.
Use 4 as the next digit of our solution. 
Result so far: 97181.4
If we take 3228 away from 4030, we end up with 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

On to step 10:
If we divide 8020 by 807, we get 9 and a remainder of 757.
Record the quotient 9 as the next digit in the result. 
Result so far: 97181.49
Subtracting 7263 from 8020 leaves us with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Moving on to step 11:
When dividing 7570 by 807, we get 9 with a remainder of 307.
The next digit of our result is 9. 
Result so far: 97181.499
If we subtract 7263 from 7570, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

In conclusion, the division gives 97181.499 with a balance of 0.0307.
