We look at the division of 21677115 by 591 
Our goal is to divide 21677115 by 591.

On to step 1:
The number 591 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 591

Going ahead to step 2:
591 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 591

On to step 3:
The number 591 fits into 216 0 times, leaving a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 216 after subtracting 0 from 216.
Grab the next digit (7) from the dividend, add it to 216, then carry on: 2167 / 591

Step 4:
If we divide 2167 by 591, we get 3 and a remainder of 394.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1773 from 2167, we get 394.
Bring next digit (7) of the dividend behind the 394 and repeat the process: 3947 / 591

Moving on to step 5:
591 goes into 3947 6 times with a remainder of 401.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 3546 from 3947 and we're left with 401.
Fetch the next digit (1) from the dividend, attach it to 401 and continue: 4011 / 591

Advancing to step 6:
When dividing 4011 by 591, we get 6 with a remainder of 465.
Use 6 as the next digit of our solution. 
Result so far: 366.0
If we subtract 3546 from 4011, we get 465.
Take the next digit (1) from the dividend and append it to 465, then repeat: 4651 / 591

Moving on to step 7:
When dividing 4651 by 591, we get 7 with a remainder of 514.
The next digit of our result is 7. 
Result so far: 3667.0
Subtracting 4137 from 4651 leaves us with 514.
Include the next digit (5) from the dividend after 514, then repeat: 5145 / 591

Step 8:
5145 divided by 591 is 8 with a remainder of 417.
The next digit of our result is 8. 
Result so far: 36678.0
If we subtract 4728 from 5145, we get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Step 9:
591 can be fit into 4170 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 36678.7
If we take 4137 away from 4170, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
The number 591 fits into 330 0 times, leaving a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 36678.7
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 11:
If we divide 3300 by 591, we get 5 and a remainder of 345.
Use 5 as the next digit of our solution. 
Result so far: 36678.705
If we take 2955 away from 3300, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 12:
When dividing 3450 by 591, we get 5 with a remainder of 495.
Write down 5 as next digit of the result. 
Result so far: 36678.7055
Subtracting 2955 from 3450 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

The final result is 36678.7055 with a remainder of 0.00495.
