We're dividing 90331091 by 578 
We want to divide 90331091 by 578.

Advancing to step 1:
The number 578 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 578

Let's proceed to step 2:
578 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 578

Advancing to step 3:
903 divided by 578 is 1 with a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 325 after subtracting 578 from 903.
Include the next digit (3) from the dividend after 325, then repeat: 3253 / 578

Let's proceed to step 4:
When dividing 3253 by 578, we get 5 with a remainder of 363.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 2890 from 3253 to get 363.
Grab the next digit (1) from the dividend, add it to 363, then carry on: 3631 / 578

Moving on to step 5:
3631 divided by 578 is 6 with a remainder of 163.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
If we subtract 3468 from 3631, we get 163.
Take the next digit (0) from the dividend and append it to 163, then repeat: 1630 / 578

Moving on to step 6:
When dividing 1630 by 578, we get 2 with a remainder of 474.
Record the quotient 2 as the next digit in the result. 
Result so far: 1562.0
Subtracting 1156 from 1630 leaves us with 474.
Fetch the next digit (9) from the dividend, attach it to 474 and continue: 4749 / 578

Going ahead to step 7:
When dividing 4749 by 578, we get 8 with a remainder of 125.
Use 8 as the next digit of our solution. 
Result so far: 15628.0
Subtracting 4624 from 4749 leaves us with 125.
Fetch the next digit (1) from the dividend, attach it to 125 and continue: 1251 / 578

Let's proceed to step 8:
The number 578 fits into 1251 2 times, leaving a remainder of 95.
Put 2 as the next digit of the answer. 
Result so far: 156282.0
Subtract 1156 from 1251 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 9:
The number 578 fits into 950 1 times, leaving a remainder of 372.
Record the quotient 1 as the next digit in the result. 
Result so far: 156282.1
If we take 578 away from 950, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 10:
3720 divided by 578 is 6 with a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 156282.16
If we subtract 3468 from 3720, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
If we divide 2520 by 578, we get 4 and a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 156282.164
The remainder is 208 after subtracting 2312 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
2080 divided by 578 is 3 with a remainder of 346.
Write down 3 as next digit of the result. 
Result so far: 156282.1643
Subtracting 1734 from 2080 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 13:
When dividing 3460 by 578, we get 5 with a remainder of 570.
Put 5 as the next digit of the answer. 
Result so far: 156282.16435
If we subtract 2890 from 3460, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 14:
578 can be fit into 5700 9 times, resulting in a remainder of 498.
Use 9 as the next digit of our solution. 
Result so far: 156282.164359
The remainder is 498 after subtracting 5202 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Let's proceed to step 15:
When dividing 4980 by 578, we get 8 with a remainder of 356.
The number 8 becomes the next digit in our result. 
Result so far: 156282.1643598
If we take 4624 away from 4980, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 16:
The number 578 fits into 3560 6 times, leaving a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 156282.16435986
Deduct 3468 from 3560 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 156282.16435986 with a remaining 9.2e-08.
