Let's divide 90178857 by 459
We want to divide 90178857 by 459.

Moving on to step 1:
If we divide 9 by 459, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 459

Going ahead to step 2:
459 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 459

Step 3:
When dividing 901 by 459, we get 1 with a remainder of 442.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 459 from 901, we get 442.
Include the next digit (7) from the dividend after 442, then repeat: 4427 / 459

Advancing to step 4:
When dividing 4427 by 459, we get 9 with a remainder of 296.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 4131 from 4427 to get 296.
Bring next digit (8) of the dividend behind the 296 and repeat the process: 2968 / 459

Step 5:
459 goes into 2968 6 times with a remainder of 214.
Use 6 as the next digit of our solution. 
Result so far: 196.0
If we subtract 2754 from 2968, we get 214.
Fetch the next digit (8) from the dividend, attach it to 214 and continue: 2148 / 459

Step 6:
If we divide 2148 by 459, we get 4 and a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 1964.0
Subtracting 1836 from 2148 leaves us with 312.
Bring next digit (5) of the dividend behind the 312 and repeat the process: 3125 / 459

Moving on to step 7:
459 goes into 3125 6 times with a remainder of 371.
The number 6 becomes the next digit in our result. 
Result so far: 19646.0
Subtracting 2754 from 3125 leaves us with 371.
Grab the next digit (7) from the dividend, add it to 371, then carry on: 3717 / 459

Going ahead to step 8:
The number 459 fits into 3717 8 times, leaving a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 196468.0
If we take 3672 away from 3717, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
459 can be fit into 450 0 times, resulting in a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 196468.0
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
459 goes into 4500 9 times with a remainder of 369.
Write down 9 as next digit of the result. 
Result so far: 196468.09
The remainder is 369 after subtracting 4131 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 11:
If we divide 3690 by 459, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 196468.098
If we take 3672 away from 3690, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
459 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 196468.098
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
The number 459 fits into 1800 3 times, leaving a remainder of 423.
Use 3 as the next digit of our solution. 
Result so far: 196468.09803
Deduct 1377 from 1800 and we're left with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Let's proceed to step 14:
4230 divided by 459 is 9 with a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 196468.098039
Subtracting 4131 from 4230 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 15:
459 goes into 990 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 196468.0980392
Subtracting 918 from 990 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 16:
459 can be fit into 720 1 times, resulting in a remainder of 261.
Use 1 as the next digit of our solution. 
Result so far: 196468.09803921
Subtract 459 from 720 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

After the division, we end up with 196468.09803921 and a remainder of 2.61e-07.
