12991527 ÷ 658 
We want to divide 12991527 by 658.

On to step 1:
When dividing 1 by 658, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
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 / 658

Advancing to step 2:
658 goes into 12 0 times 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.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 658

Let's proceed to step 3:
If we divide 129 by 658, we get 0 and a remainder of 129.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 129 leaves us with 129.
Fetch the next digit (9) from the dividend, attach it to 129 and continue: 1299 / 658

Going ahead to step 4:
If we divide 1299 by 658, we get 1 and a remainder of 641.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 658 away from 1299, we end up with 641.
Append the next digit (1) from the dividend to 641 and continue with: 6411 / 658

Step 5:
The number 658 fits into 6411 9 times, leaving a remainder of 489.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 5922 from 6411, we get 489.
Fetch the next digit (5) from the dividend, attach it to 489 and continue: 4895 / 658

Advancing to step 6:
658 goes into 4895 7 times with a remainder of 289.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Subtract 4606 from 4895 to get 289.
Take the next digit (2) from the dividend and append it to 289, then repeat: 2892 / 658

Moving on to step 7:
If we divide 2892 by 658, we get 4 and a remainder of 260.
Use 4 as the next digit of our solution. 
Result so far: 1974.0
If we take 2632 away from 2892, we end up with 260.
Grab the next digit (7) from the dividend, add it to 260, then carry on: 2607 / 658

Step 8:
2607 divided by 658 is 3 with a remainder of 633.
Put 3 as the next digit of the answer. 
Result so far: 19743.0
Deduct 1974 from 2607 and we're left with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Advancing to step 9:
658 goes into 6330 9 times with a remainder of 408.
Record the quotient 9 as the next digit in the result. 
Result so far: 19743.9
If we subtract 5922 from 6330, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 10:
The number 658 fits into 4080 6 times, leaving a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 19743.96
If we take 3948 away from 4080, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 11:
When dividing 1320 by 658, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 19743.962
If we take 1316 away from 1320, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
If we divide 40 by 658, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 19743.962
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
If we divide 400 by 658, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 19743.962
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 19743.962 with a remaining 0.0004.
