We divide 21679415 by 591
We want to divide 21679415 by 591.

Step 1:
If we divide 2 by 591, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 591

Moving on to step 2:
When dividing 21 by 591, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 591

Let's proceed to step 3:
When dividing 216 by 591, we get 0 with a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 216 after subtracting 0 from 216.
Take the next digit (7) from the dividend and append it to 216, then repeat: 2167 / 591

Going ahead to step 4:
591 goes into 2167 3 times with a remainder of 394.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1773 from 2167 to get 394.
Fetch the next digit (9) from the dividend, attach it to 394 and continue: 3949 / 591

Moving on to step 5:
If we divide 3949 by 591, we get 6 and a remainder of 403.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 3546 from 3949 and we're left with 403.
Take the next digit (4) from the dividend and append it to 403, then repeat: 4034 / 591

Moving on to step 6:
591 can be fit into 4034 6 times, resulting in a remainder of 488.
The number 6 becomes the next digit in our result. 
Result so far: 366.0
Deduct 3546 from 4034 and we're left with 488.
Fetch the next digit (1) from the dividend, attach it to 488 and continue: 4881 / 591

Let's proceed to step 7:
When dividing 4881 by 591, we get 8 with a remainder of 153.
Put 8 as the next digit of the answer. 
Result so far: 3668.0
The remainder is 153 after subtracting 4728 from 4881.
Grab the next digit (5) from the dividend, add it to 153, then carry on: 1535 / 591

Step 8:
1535 divided by 591 is 2 with a remainder of 353.
Put 2 as the next digit of the answer. 
Result so far: 36682.0
Deduct 1182 from 1535 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 9:
When dividing 3530 by 591, we get 5 with a remainder of 575.
Put 5 as the next digit of the answer. 
Result so far: 36682.5
Subtract 2955 from 3530 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 10:
When dividing 5750 by 591, we get 9 with a remainder of 431.
Record the quotient 9 as the next digit in the result. 
Result so far: 36682.59
If we take 5319 away from 5750, we end up with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Step 11:
If we divide 4310 by 591, we get 7 and a remainder of 173.
Use 7 as the next digit of our solution. 
Result so far: 36682.597
The remainder is 173 after subtracting 4137 from 4310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 12:
When dividing 1730 by 591, we get 2 with a remainder of 548.
Put 2 as the next digit of the answer. 
Result so far: 36682.5972
Subtracting 1182 from 1730 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 13:
The number 591 fits into 5480 9 times, leaving a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 36682.59729
Subtracting 5319 from 5480 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 14:
If we divide 1610 by 591, we get 2 and a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 36682.597292
If we subtract 1182 from 1610, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 15:
If we divide 4280 by 591, we get 7 and a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 36682.5972927
Subtracting 4137 from 4280 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 16:
1430 divided by 591 is 2 with a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 36682.59729272
Subtracting 1182 from 1430 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final outcome is 36682.59729272, with a leftover of 2.48e-07.
