We're dividing 81221629 by 587 
Our goal is to divide 81221629 by 587.

Let's proceed to step 1:
8 divided by 587 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 587

Let's proceed to step 2:
587 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 587

Going ahead to step 3:
The number 587 fits into 812 1 times, leaving a remainder of 225.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 225 after subtracting 587 from 812.
Fetch the next digit (2) from the dividend, attach it to 225 and continue: 2252 / 587

Let's proceed to step 4:
If we divide 2252 by 587, we get 3 and a remainder of 491.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 1761 from 2252 and we're left with 491.
Include the next digit (1) from the dividend after 491, then repeat: 4911 / 587

Let's proceed to step 5:
587 goes into 4911 8 times with a remainder of 215.
Write down 8 as next digit of the result. 
Result so far: 138.0
Subtract 4696 from 4911 to get 215.
Include the next digit (6) from the dividend after 215, then repeat: 2156 / 587

Let's proceed to step 6:
When dividing 2156 by 587, we get 3 with a remainder of 395.
Put 3 as the next digit of the answer. 
Result so far: 1383.0
The remainder is 395 after subtracting 1761 from 2156.
Include the next digit (2) from the dividend after 395, then repeat: 3952 / 587

Let's proceed to step 7:
3952 divided by 587 is 6 with a remainder of 430.
Put 6 as the next digit of the answer. 
Result so far: 13836.0
Deduct 3522 from 3952 and we're left with 430.
Bring next digit (9) of the dividend behind the 430 and repeat the process: 4309 / 587

Step 8:
If we divide 4309 by 587, we get 7 and a remainder of 200.
The number 7 becomes the next digit in our result. 
Result so far: 138367.0
Subtract 4109 from 4309 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 9:
587 goes into 2000 3 times with a remainder of 239.
The number 3 becomes the next digit in our result. 
Result so far: 138367.3
Subtracting 1761 from 2000 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 10:
The number 587 fits into 2390 4 times, leaving a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 138367.34
Deduct 2348 from 2390 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
587 goes into 420 0 times with a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 138367.34
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 12:
4200 divided by 587 is 7 with a remainder of 91.
Write down 7 as next digit of the result. 
Result so far: 138367.3407
If we take 4109 away from 4200, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 13:
If we divide 910 by 587, we get 1 and a remainder of 323.
The next digit of our result is 1. 
Result so far: 138367.34071
Subtract 587 from 910 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 14:
If we divide 3230 by 587, we get 5 and a remainder of 295.
The next digit of our result is 5. 
Result so far: 138367.340715
If we subtract 2935 from 3230, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 15:
If we divide 2950 by 587, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 138367.3407155
The remainder is 15 after subtracting 2935 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 138367.3407155 with a remaining 1.5e-07.
