Let's divide 39149417 by 129
We're looking to find how many times 129 goes into 39149417.

On to step 1:
129 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 129

Step 2:
The number 129 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 129

Advancing to step 3:
If we divide 391 by 129, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 387 away from 391, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 129

Going ahead to step 4:
44 divided by 129 is 0 with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 44 and we're left with 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 129

Step 5:
If we divide 449 by 129, we get 3 and a remainder of 62.
The next digit of our result is 3. 
Result so far: 303.0
Deduct 387 from 449 and we're left with 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 129

Let's proceed to step 6:
624 divided by 129 is 4 with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 3034.0
If we subtract 516 from 624, we get 108.
Take the next digit (1) from the dividend and append it to 108, then repeat: 1081 / 129

Step 7:
129 goes into 1081 8 times with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 30348.0
If we subtract 1032 from 1081, we get 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 129

Let's proceed to step 8:
When dividing 497 by 129, we get 3 with a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 303483.0
If we take 387 away from 497, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 9:
If we divide 1100 by 129, we get 8 and a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 303483.8
If we subtract 1032 from 1100, 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.

Let's proceed to step 10:
The number 129 fits into 680 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 303483.85
Subtract 645 from 680 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
The number 129 fits into 350 2 times, leaving a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 303483.852
Subtracting 258 from 350 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 12:
129 goes into 920 7 times with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 303483.8527
If we subtract 903 from 920, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
170 divided by 129 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 303483.85271
Subtracting 129 from 170 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 14:
The number 129 fits into 410 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 303483.852713
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 15:
129 can be fit into 230 1 times, resulting in a remainder of 101.
The next digit of our result is 1. 
Result so far: 303483.8527131
If we subtract 129 from 230, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 16:
129 goes into 1010 7 times with a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 303483.85271317
Subtracting 903 from 1010 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

After the division, we end up with 303483.85271317 and a remainder of 1.07e-07.
