We look at the division of 15985815 by 455 
Our goal is to divide 15985815 by 455.

Moving on to step 1:
1 divided by 455 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 455

Advancing to step 2:
If we divide 15 by 455, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 455

Advancing to step 3:
If we divide 159 by 455, we get 0 and a remainder of 159.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 159, we get 159.
Append the next digit (8) from the dividend to 159 and continue with: 1598 / 455

Step 4:
455 goes into 1598 3 times with a remainder of 233.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1365 away from 1598, we end up with 233.
Fetch the next digit (5) from the dividend, attach it to 233 and continue: 2335 / 455

On to step 5:
If we divide 2335 by 455, we get 5 and a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 2275 from 2335 and we're left with 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 455

Going ahead to step 6:
If we divide 608 by 455, we get 1 and a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 351.0
The remainder is 153 after subtracting 455 from 608.
Grab the next digit (1) from the dividend, add it to 153, then carry on: 1531 / 455

Going ahead to step 7:
If we divide 1531 by 455, we get 3 and a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 3513.0
The remainder is 166 after subtracting 1365 from 1531.
Bring next digit (5) of the dividend behind the 166 and repeat the process: 1665 / 455

On to step 8:
If we divide 1665 by 455, we get 3 and a remainder of 300.
The number 3 becomes the next digit in our result. 
Result so far: 35133.0
Subtracting 1365 from 1665 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 9:
When dividing 3000 by 455, we get 6 with a remainder of 270.
The next digit of our result is 6. 
Result so far: 35133.6
If we subtract 2730 from 3000, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
If we divide 2700 by 455, we get 5 and a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 35133.65
If we take 2275 away from 2700, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 11:
455 can be fit into 4250 9 times, resulting in a remainder of 155.
Use 9 as the next digit of our solution. 
Result so far: 35133.659
The remainder is 155 after subtracting 4095 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 12:
1550 divided by 455 is 3 with a remainder of 185.
The number 3 becomes the next digit in our result. 
Result so far: 35133.6593
Subtracting 1365 from 1550 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 13:
455 can be fit into 1850 4 times, resulting in a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 35133.65934
If we subtract 1820 from 1850, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
300 divided by 455 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 35133.65934
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 15:
When dividing 3000 by 455, we get 6 with a remainder of 270.
Record the quotient 6 as the next digit in the result. 
Result so far: 35133.6593406
Deduct 2730 from 3000 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 16:
The number 455 fits into 2700 5 times, leaving a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 35133.65934065
If we subtract 2275 from 2700, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

In conclusion, the division gives 35133.65934065 with a balance of 4.25e-07.
