648030 ÷ 91 
Let's see how many times 91 fits into 648030.

Advancing to step 1:
6 divided by 91 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 91

Going ahead to step 2:
91 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 91

On to step 3:
If we divide 648 by 91, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 637 from 648 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 91

Let's proceed to step 4:
91 goes into 110 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Deduct 91 from 110 and we're left with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 91

Let's proceed to step 5:
91 can be fit into 193 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 712.0
The remainder is 11 after subtracting 182 from 193.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 91

Let's proceed to step 6:
If we divide 110 by 91, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 7121.0
Deduct 91 from 110 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
If we divide 190 by 91, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 7121.2
If we take 182 away from 190, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
When dividing 80 by 91, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 7121.2
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
91 goes into 800 8 times with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 7121.208
Deduct 728 from 800 and we're left 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.

Going ahead to step 10:
If we divide 720 by 91, we get 7 and a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 7121.2087
Deduct 637 from 720 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 11:
91 goes into 830 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 7121.20879
Subtract 819 from 830 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
If we divide 110 by 91, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 7121.208791
Subtract 91 from 110 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
The number 91 fits into 190 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 7121.2087912
If we take 182 away from 190, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
80 divided by 91 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 7121.2087912
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 7121.2087912 and a remainder of 8e-08.
