We're dividing 91014517 by 578 
Let's see how many times 578 fits into 91014517.

Let's proceed to step 1:
When dividing 9 by 578, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 578

Moving on to step 2:
If we divide 91 by 578, we get 0 and a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 578

Step 3:
The number 578 fits into 910 1 times, leaving a remainder of 332.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 578 from 910, we get 332.
Include the next digit (1) from the dividend after 332, then repeat: 3321 / 578

Moving on to step 4:
The number 578 fits into 3321 5 times, leaving a remainder of 431.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 2890 from 3321, we get 431.
Grab the next digit (4) from the dividend, add it to 431, then carry on: 4314 / 578

Going ahead to step 5:
The number 578 fits into 4314 7 times, leaving a remainder of 268.
Put 7 as the next digit of the answer. 
Result so far: 157.0
Subtract 4046 from 4314 to get 268.
Fetch the next digit (5) from the dividend, attach it to 268 and continue: 2685 / 578

Step 6:
The number 578 fits into 2685 4 times, leaving a remainder of 373.
Write down 4 as next digit of the result. 
Result so far: 1574.0
Subtract 2312 from 2685 to get 373.
Grab the next digit (1) from the dividend, add it to 373, then carry on: 3731 / 578

Advancing to step 7:
If we divide 3731 by 578, we get 6 and a remainder of 263.
The number 6 becomes the next digit in our result. 
Result so far: 15746.0
Deduct 3468 from 3731 and we're left with 263.
Include the next digit (7) from the dividend after 263, then repeat: 2637 / 578

Going ahead to step 8:
If we divide 2637 by 578, we get 4 and a remainder of 325.
Record the quotient 4 as the next digit in the result. 
Result so far: 157464.0
Subtracting 2312 from 2637 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 9:
578 goes into 3250 5 times with a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 157464.5
If we take 2890 away from 3250, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
If we divide 3600 by 578, we get 6 and a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 157464.56
Deduct 3468 from 3600 and we're left 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.

Step 11:
1320 divided by 578 is 2 with a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 157464.562
If we take 1156 away from 1320, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 12:
When dividing 1640 by 578, we get 2 with a remainder of 484.
The number 2 becomes the next digit in our result. 
Result so far: 157464.5622
If we subtract 1156 from 1640, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Our division results in 157464.5622 with a remaining 0.00484.
