We divide 12079889 by 646
We want to divide 12079889 by 646.

On to step 1:
1 divided by 646 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 646

Let's proceed to step 2:
12 divided by 646 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 646

Step 3:
When dividing 120 by 646, we get 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Fetch the next digit (7) from the dividend, attach it to 120 and continue: 1207 / 646

Advancing to step 4:
When dividing 1207 by 646, we get 1 with a remainder of 561.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 646 from 1207 leaves us with 561.
Grab the next digit (9) from the dividend, add it to 561, then carry on: 5619 / 646

Going ahead to step 5:
5619 divided by 646 is 8 with a remainder of 451.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 5168 away from 5619, we end up with 451.
Fetch the next digit (8) from the dividend, attach it to 451 and continue: 4518 / 646

Advancing to step 6:
The number 646 fits into 4518 6 times, leaving a remainder of 642.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
If we take 3876 away from 4518, we end up with 642.
Include the next digit (8) from the dividend after 642, then repeat: 6428 / 646

On to step 7:
If we divide 6428 by 646, we get 9 and a remainder of 614.
Use 9 as the next digit of our solution. 
Result so far: 1869.0
The remainder is 614 after subtracting 5814 from 6428.
Take the next digit (9) from the dividend and append it to 614, then repeat: 6149 / 646

Let's proceed to step 8:
646 can be fit into 6149 9 times, resulting in a remainder of 335.
Use 9 as the next digit of our solution. 
Result so far: 18699.0
If we take 5814 away from 6149, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 9:
646 goes into 3350 5 times with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 18699.5
Subtracting 3230 from 3350 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
The number 646 fits into 1200 1 times, leaving a remainder of 554.
Put 1 as the next digit of the answer. 
Result so far: 18699.51
Deduct 646 from 1200 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 11:
5540 divided by 646 is 8 with a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 18699.518
If we take 5168 away from 5540, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 12:
If we divide 3720 by 646, we get 5 and a remainder of 490.
Put 5 as the next digit of the answer. 
Result so far: 18699.5185
Subtract 3230 from 3720 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 13:
If we divide 4900 by 646, we get 7 and a remainder of 378.
Write down 7 as next digit of the result. 
Result so far: 18699.51857
Deduct 4522 from 4900 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 14:
3780 divided by 646 is 5 with a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 18699.518575
The remainder is 550 after subtracting 3230 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 15:
5500 divided by 646 is 8 with a remainder of 332.
The number 8 becomes the next digit in our result. 
Result so far: 18699.5185758
The remainder is 332 after subtracting 5168 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 16:
The number 646 fits into 3320 5 times, leaving a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 18699.51857585
If we subtract 3230 from 3320, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 18699.51857585 with a remainder of 9e-08.
