Let's divide 39886347 by 629
We want to divide 39886347 by 629.

Step 1:
If we divide 3 by 629, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 629

On to step 2:
629 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 629

On to step 3:
629 can be fit into 398 0 times, resulting in a remainder of 398.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 398 after subtracting 0 from 398.
Bring next digit (8) of the dividend behind the 398 and repeat the process: 3988 / 629

Moving on to step 4:
3988 divided by 629 is 6 with a remainder of 214.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 3774 from 3988 to get 214.
Append the next digit (6) from the dividend to 214 and continue with: 2146 / 629

On to step 5:
If we divide 2146 by 629, we get 3 and a remainder of 259.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 1887 from 2146 leaves us with 259.
Bring next digit (3) of the dividend behind the 259 and repeat the process: 2593 / 629

On to step 6:
2593 divided by 629 is 4 with a remainder of 77.
Use 4 as the next digit of our solution. 
Result so far: 634.0
Subtracting 2516 from 2593 leaves us with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 629

Let's proceed to step 7:
629 can be fit into 774 1 times, resulting in a remainder of 145.
Put 1 as the next digit of the answer. 
Result so far: 6341.0
If we subtract 629 from 774, we get 145.
Take the next digit (7) from the dividend and append it to 145, then repeat: 1457 / 629

Let's proceed to step 8:
When dividing 1457 by 629, we get 2 with a remainder of 199.
Write down 2 as next digit of the result. 
Result so far: 63412.0
Subtract 1258 from 1457 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 9:
When dividing 1990 by 629, we get 3 with a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 63412.3
The remainder is 103 after subtracting 1887 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 10:
If we divide 1030 by 629, we get 1 and a remainder of 401.
The number 1 becomes the next digit in our result. 
Result so far: 63412.31
The remainder is 401 after subtracting 629 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 11:
If we divide 4010 by 629, we get 6 and a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 63412.316
The remainder is 236 after subtracting 3774 from 4010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 12:
629 can be fit into 2360 3 times, resulting in a remainder of 473.
Put 3 as the next digit of the answer. 
Result so far: 63412.3163
Deduct 1887 from 2360 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 13:
If we divide 4730 by 629, we get 7 and a remainder of 327.
Record the quotient 7 as the next digit in the result. 
Result so far: 63412.31637
The remainder is 327 after subtracting 4403 from 4730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 14:
629 can be fit into 3270 5 times, resulting in a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 63412.316375
Subtracting 3145 from 3270 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 15:
1250 divided by 629 is 1 with a remainder of 621.
Use 1 as the next digit of our solution. 
Result so far: 63412.3163751
Subtract 629 from 1250 to get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Step 16:
When dividing 6210 by 629, we get 9 with a remainder of 549.
Put 9 as the next digit of the answer. 
Result so far: 63412.31637519
Subtracting 5661 from 6210 leaves us with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

The final result is 63412.31637519 with a remainder of 5.49e-07.
