We're dividing 629146 by 86 
We want to figure out the number of times 629146 can be divided by 86.

Going ahead to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 86

Moving on to step 2:
The number 86 fits into 62 0 times, leaving a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Grab the next digit (9) from the dividend, add it to 62, then carry on: 629 / 86

Advancing to step 3:
86 goes into 629 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 602 from 629 and we're left with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 86

Advancing to step 4:
The number 86 fits into 271 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 73.0
The remainder is 13 after subtracting 258 from 271.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 86

Step 5:
134 divided by 86 is 1 with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 731.0
If we take 86 away from 134, we end up with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 86

Moving on to step 6:
When dividing 486 by 86, we get 5 with a remainder of 56.
Use 5 as the next digit of our solution. 
Result so far: 7315.0
If we subtract 430 from 486, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
When dividing 560 by 86, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 7315.6
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 7315.65
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 86, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 7315.651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 7315.6511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 7315.6511, and the remainder is 0.00054.
