We're dividing 86430266 by 628 
We're looking to find how many times 628 goes into 86430266.

Going ahead to step 1:
The number 628 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 628

On to step 2:
86 divided by 628 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 628

Let's proceed to step 3:
If we divide 864 by 628, we get 1 and a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 628 from 864 leaves us with 236.
Append the next digit (3) from the dividend to 236 and continue with: 2363 / 628

Going ahead to step 4:
If we divide 2363 by 628, we get 3 and a remainder of 479.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1884 from 2363 and we're left with 479.
Include the next digit (0) from the dividend after 479, then repeat: 4790 / 628

Moving on to step 5:
The number 628 fits into 4790 7 times, leaving a remainder of 394.
Use 7 as the next digit of our solution. 
Result so far: 137.0
If we subtract 4396 from 4790, we get 394.
Bring next digit (2) of the dividend behind the 394 and repeat the process: 3942 / 628

On to step 6:
If we divide 3942 by 628, we get 6 and a remainder of 174.
Use 6 as the next digit of our solution. 
Result so far: 1376.0
Subtract 3768 from 3942 to get 174.
Include the next digit (6) from the dividend after 174, then repeat: 1746 / 628

Going ahead to step 7:
628 goes into 1746 2 times with a remainder of 490.
The number 2 becomes the next digit in our result. 
Result so far: 13762.0
If we subtract 1256 from 1746, we get 490.
Take the next digit (6) from the dividend and append it to 490, then repeat: 4906 / 628

Step 8:
4906 divided by 628 is 7 with a remainder of 510.
Put 7 as the next digit of the answer. 
Result so far: 137627.0
If we subtract 4396 from 4906, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 9:
When dividing 5100 by 628, we get 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 137627.8
Subtracting 5024 from 5100 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
The number 628 fits into 760 1 times, leaving a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 137627.81
Subtracting 628 from 760 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 11:
When dividing 1320 by 628, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 137627.812
If we subtract 1256 from 1320, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
628 goes into 640 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 137627.8121
If we take 628 away from 640, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
If we divide 120 by 628, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 137627.8121
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 14:
The number 628 fits into 1200 1 times, leaving a remainder of 572.
Put 1 as the next digit of the answer. 
Result so far: 137627.812101
Subtracting 628 from 1200 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 15:
5720 divided by 628 is 9 with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 137627.8121019
If we take 5652 away from 5720, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 16:
628 can be fit into 680 1 times, resulting in a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 137627.81210191
The remainder is 52 after subtracting 628 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 137627.81210191 with a balance of 5.2e-08.
