Let's divide 81769777 by 21
We want to divide 81769777 by 21.

Let's proceed to step 1:
21 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 21

Moving on to step 2:
When dividing 81 by 21, we get 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 63 away from 81, we end up with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 21

Going ahead to step 3:
The number 21 fits into 187 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 168 from 187 and we're left with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 21

On to step 4:
196 divided by 21 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 389.0
If we take 189 away from 196, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 21

Step 5:
The number 21 fits into 79 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 3893.0
Deduct 63 from 79 and we're left with 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 21

Going ahead to step 6:
21 can be fit into 167 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 38937.0
Subtracting 147 from 167 leaves us with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 21

Advancing to step 7:
207 divided by 21 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 389379.0
Subtracting 189 from 207 leaves us with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 21

Moving on to step 8:
The number 21 fits into 187 8 times, leaving a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 3893798.0
Subtracting 168 from 187 leaves us 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.

Moving on to step 9:
21 goes into 190 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3893798.9
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3893798.9
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
When dividing 100 by 21, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 3893798.904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3893798.9047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 3893798.90476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
40 divided by 21 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 3893798.904761
If we subtract 21 from 40, we 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.

Moving on to step 15:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 3893798.9047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 16:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 3893798.9047619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 3893798.9047619 and a remainder of 1e-08.
