12708685 divided by 428 
We want to divide 12708685 by 428.

Let's proceed to step 1:
When dividing 1 by 428, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 428

On to step 2:
When dividing 12 by 428, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 428

Step 3:
When dividing 127 by 428, we get 0 with a remainder of 127.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 127 after subtracting 0 from 127.
Grab the next digit (0) from the dividend, add it to 127, then carry on: 1270 / 428

Step 4:
1270 divided by 428 is 2 with a remainder of 414.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 856 from 1270 and we're left with 414.
Take the next digit (8) from the dividend and append it to 414, then repeat: 4148 / 428

On to step 5:
4148 divided by 428 is 9 with a remainder of 296.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Deduct 3852 from 4148 and we're left with 296.
Grab the next digit (6) from the dividend, add it to 296, then carry on: 2966 / 428

Step 6:
When dividing 2966 by 428, we get 6 with a remainder of 398.
Use 6 as the next digit of our solution. 
Result so far: 296.0
If we subtract 2568 from 2966, we get 398.
Bring next digit (8) of the dividend behind the 398 and repeat the process: 3988 / 428

Advancing to step 7:
428 can be fit into 3988 9 times, resulting in a remainder of 136.
Write down 9 as next digit of the result. 
Result so far: 2969.0
Subtract 3852 from 3988 to get 136.
Fetch the next digit (5) from the dividend, attach it to 136 and continue: 1365 / 428

Moving on to step 8:
428 can be fit into 1365 3 times, resulting in a remainder of 81.
Write down 3 as next digit of the result. 
Result so far: 29693.0
The remainder is 81 after subtracting 1284 from 1365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
If we divide 810 by 428, we get 1 and a remainder of 382.
Write down 1 as next digit of the result. 
Result so far: 29693.1
Subtract 428 from 810 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 10:
428 can be fit into 3820 8 times, resulting in a remainder of 396.
Use 8 as the next digit of our solution. 
Result so far: 29693.18
Deduct 3424 from 3820 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 11:
3960 divided by 428 is 9 with a remainder of 108.
Put 9 as the next digit of the answer. 
Result so far: 29693.189
If we take 3852 away from 3960, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 12:
The number 428 fits into 1080 2 times, leaving a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 29693.1892
The remainder is 224 after subtracting 856 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 13:
When dividing 2240 by 428, we get 5 with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 29693.18925
Subtracting 2140 from 2240 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
428 can be fit into 1000 2 times, resulting in a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 29693.189252
If we subtract 856 from 1000, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 15:
When dividing 1440 by 428, we get 3 with a remainder of 156.
The number 3 becomes the next digit in our result. 
Result so far: 29693.1892523
Subtracting 1284 from 1440 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 16:
If we divide 1560 by 428, we get 3 and a remainder of 276.
Write down 3 as next digit of the result. 
Result so far: 29693.18925233
Subtract 1284 from 1560 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 29693.18925233 and a remainder of 2.76e-07.
