629455 divided by 86 
We're looking to find how many times 86 goes into 629455.

Going ahead to step 1:
86 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 86

On to step 2:
If we divide 62 by 86, we get 0 and a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 86

Let's proceed to step 3:
86 goes into 629 7 times with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 602 from 629 leaves us with 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 86

Step 4:
The number 86 fits into 274 3 times, leaving a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 73.0
Deduct 258 from 274 and we're left with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 86

Step 5:
86 can be fit into 165 1 times, resulting in a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 731.0
If we take 86 away from 165, we end up with 79.
Grab the next digit (5) from the dividend, add it to 79, then carry on: 795 / 86

Going ahead to step 6:
795 divided by 86 is 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 7319.0
The remainder is 21 after subtracting 774 from 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
The number 86 fits into 210 2 times, leaving a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 7319.2
Subtracting 172 from 210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
When dividing 380 by 86, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 7319.24
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
When dividing 360 by 86, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 7319.244
If we take 344 away from 360, we end up 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.

After the division, we end up with 7319.244 and a remainder of 0.0016.
