We divide 86664130 by 629
Our goal is to divide 86664130 by 629.

Let's proceed to step 1:
When dividing 8 by 629, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 629

Advancing to step 2:
The number 629 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 629

Going ahead to step 3:
629 goes into 866 1 times with a remainder of 237.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 237 after subtracting 629 from 866.
Include the next digit (6) from the dividend after 237, then repeat: 2376 / 629

Advancing to step 4:
629 goes into 2376 3 times with a remainder of 489.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1887 from 2376 leaves us with 489.
Append the next digit (4) from the dividend to 489 and continue with: 4894 / 629

Step 5:
The number 629 fits into 4894 7 times, leaving a remainder of 491.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Deduct 4403 from 4894 and we're left with 491.
Fetch the next digit (1) from the dividend, attach it to 491 and continue: 4911 / 629

Let's proceed to step 6:
The number 629 fits into 4911 7 times, leaving a remainder of 508.
Record the quotient 7 as the next digit in the result. 
Result so far: 1377.0
If we take 4403 away from 4911, we end up with 508.
Append the next digit (3) from the dividend to 508 and continue with: 5083 / 629

Let's proceed to step 7:
5083 divided by 629 is 8 with a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 13778.0
If we subtract 5032 from 5083, we get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 629

On to step 8:
510 divided by 629 is 0 with a remainder of 510.
Record the quotient 0 as the next digit in the result. 
Result so far: 137780.0
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 9:
The number 629 fits into 5100 8 times, leaving a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 137780.8
If we subtract 5032 from 5100, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
If we divide 680 by 629, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 137780.81
If we take 629 away from 680, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
When dividing 510 by 629, we get 0 with a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 137780.81
If we subtract 0 from 510, 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.

Let's proceed to step 12:
When dividing 5100 by 629, we get 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 137780.8108
Deduct 5032 from 5100 and we're left 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.

Step 13:
629 can be fit into 680 1 times, resulting in a remainder of 51.
The next digit of our result is 1. 
Result so far: 137780.81081
Subtracting 629 from 680 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 14:
The number 629 fits into 510 0 times, leaving a remainder of 510.
Put 0 as the next digit of the answer. 
Result so far: 137780.81081
Deduct 0 from 510 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 15:
If we divide 5100 by 629, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 137780.8108108
The remainder is 68 after subtracting 5032 from 5100.
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:
629 can be fit into 680 1 times, resulting in a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 137780.81081081
Deduct 629 from 680 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 137780.81081081, with a leftover of 5.1e-08.
