15972091 divided by 658 
Our goal is to divide 15972091 by 658.

On to step 1:
The number 658 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 658

On to step 2:
The number 658 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 658

Going ahead to step 3:
159 divided by 658 is 0 with a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 159 and we're left with 159.
Append the next digit (7) from the dividend to 159 and continue with: 1597 / 658

Advancing to step 4:
658 goes into 1597 2 times with a remainder of 281.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1316 from 1597 leaves us with 281.
Take the next digit (2) from the dividend and append it to 281, then repeat: 2812 / 658

Moving on to step 5:
When dividing 2812 by 658, we get 4 with a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 2632 from 2812 and we're left with 180.
Grab the next digit (0) from the dividend, add it to 180, then carry on: 1800 / 658

Moving on to step 6:
The number 658 fits into 1800 2 times, leaving a remainder of 484.
Use 2 as the next digit of our solution. 
Result so far: 242.0
Subtracting 1316 from 1800 leaves us with 484.
Append the next digit (9) from the dividend to 484 and continue with: 4849 / 658

Moving on to step 7:
658 can be fit into 4849 7 times, resulting in a remainder of 243.
The next digit of our result is 7. 
Result so far: 2427.0
If we take 4606 away from 4849, we end up with 243.
Grab the next digit (1) from the dividend, add it to 243, then carry on: 2431 / 658

Step 8:
If we divide 2431 by 658, we get 3 and a remainder of 457.
Record the quotient 3 as the next digit in the result. 
Result so far: 24273.0
Subtracting 1974 from 2431 leaves us with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

On to step 9:
When dividing 4570 by 658, we get 6 with a remainder of 622.
Record the quotient 6 as the next digit in the result. 
Result so far: 24273.6
The remainder is 622 after subtracting 3948 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 10:
If we divide 6220 by 658, we get 9 and a remainder of 298.
The next digit of our result is 9. 
Result so far: 24273.69
The remainder is 298 after subtracting 5922 from 6220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 11:
The number 658 fits into 2980 4 times, leaving a remainder of 348.
Put 4 as the next digit of the answer. 
Result so far: 24273.694
Subtracting 2632 from 2980 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 12:
658 can be fit into 3480 5 times, resulting in a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 24273.6945
Subtract 3290 from 3480 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 13:
658 goes into 1900 2 times with a remainder of 584.
The next digit of our result is 2. 
Result so far: 24273.69452
Deduct 1316 from 1900 and we're left with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 14:
When dividing 5840 by 658, we get 8 with a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 24273.694528
The remainder is 576 after subtracting 5264 from 5840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 15:
658 goes into 5760 8 times with a remainder of 496.
The number 8 becomes the next digit in our result. 
Result so far: 24273.6945288
Subtract 5264 from 5760 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

After the division, we end up with 24273.6945288 and a remainder of 4.96e-06.
