We divide 64470307 by 428
We're looking to find how many times 428 goes into 64470307.

Going ahead to step 1:
428 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 428

Step 2:
428 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 428

Let's proceed to step 3:
428 goes into 644 1 times with a remainder of 216.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 216 after subtracting 428 from 644.
Take the next digit (7) from the dividend and append it to 216, then repeat: 2167 / 428

On to step 4:
428 can be fit into 2167 5 times, resulting in a remainder of 27.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 2140 from 2167 to get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 428

Step 5:
270 divided by 428 is 0 with a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtract 0 from 270 to get 270.
Bring next digit (3) of the dividend behind the 270 and repeat the process: 2703 / 428

On to step 6:
If we divide 2703 by 428, we get 6 and a remainder of 135.
Write down 6 as next digit of the result. 
Result so far: 1506.0
Subtract 2568 from 2703 to get 135.
Fetch the next digit (0) from the dividend, attach it to 135 and continue: 1350 / 428

Let's proceed to step 7:
When dividing 1350 by 428, we get 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 15063.0
If we subtract 1284 from 1350, we get 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 428

Going ahead to step 8:
The number 428 fits into 667 1 times, leaving a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 150631.0
If we take 428 away from 667, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 9:
When dividing 2390 by 428, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 150631.5
Subtract 2140 from 2390 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
428 goes into 2500 5 times with a remainder of 360.
Use 5 as the next digit of our solution. 
Result so far: 150631.55
If we subtract 2140 from 2500, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 150631.55 with a balance of 0.36.
