We divide 12689600 by 988
We're looking to find how many times 988 goes into 12689600.

On to step 1:
If we divide 1 by 988, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 988

Going ahead to step 2:
When dividing 12 by 988, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 988

Let's proceed to step 3:
When dividing 126 by 988, we get 0 with a remainder of 126.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 126 after subtracting 0 from 126.
Append the next digit (8) from the dividend to 126 and continue with: 1268 / 988

Advancing to step 4:
1268 divided by 988 is 1 with a remainder of 280.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 988 from 1268 to get 280.
Bring next digit (9) of the dividend behind the 280 and repeat the process: 2809 / 988

Going ahead to step 5:
When dividing 2809 by 988, we get 2 with a remainder of 833.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 833 after subtracting 1976 from 2809.
Append the next digit (6) from the dividend to 833 and continue with: 8336 / 988

Let's proceed to step 6:
The number 988 fits into 8336 8 times, leaving a remainder of 432.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we take 7904 away from 8336, we end up with 432.
Include the next digit (0) from the dividend after 432, then repeat: 4320 / 988

On to step 7:
988 goes into 4320 4 times with a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 1284.0
Subtracting 3952 from 4320 leaves us with 368.
Append the next digit (0) from the dividend to 368 and continue with: 3680 / 988

Going ahead to step 8:
988 goes into 3680 3 times with a remainder of 716.
The next digit of our result is 3. 
Result so far: 12843.0
If we take 2964 away from 3680, we end up with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 9:
The number 988 fits into 7160 7 times, leaving a remainder of 244.
Use 7 as the next digit of our solution. 
Result so far: 12843.7
Subtracting 6916 from 7160 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 10:
988 goes into 2440 2 times with a remainder of 464.
The next digit of our result is 2. 
Result so far: 12843.72
The remainder is 464 after subtracting 1976 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 11:
4640 divided by 988 is 4 with a remainder of 688.
Use 4 as the next digit of our solution. 
Result so far: 12843.724
The remainder is 688 after subtracting 3952 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 12:
6880 divided by 988 is 6 with a remainder of 952.
Use 6 as the next digit of our solution. 
Result so far: 12843.7246
If we take 5928 away from 6880, we end up with 952.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9520, and continue the process.

Let's proceed to step 13:
The number 988 fits into 9520 9 times, leaving a remainder of 628.
Write down 9 as next digit of the result. 
Result so far: 12843.72469
Deduct 8892 from 9520 and we're left with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 14:
When dividing 6280 by 988, we get 6 with a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 12843.724696
Deduct 5928 from 6280 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 15:
If we divide 3520 by 988, we get 3 and a remainder of 556.
The number 3 becomes the next digit in our result. 
Result so far: 12843.7246963
The remainder is 556 after subtracting 2964 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 16:
When dividing 5560 by 988, we get 5 with a remainder of 620.
Use 5 as the next digit of our solution. 
Result so far: 12843.72469635
Deduct 4940 from 5560 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

After the division, we end up with 12843.72469635 and a remainder of 6.2e-07.
