We're dividing 75681677 by 21 
Our goal is to divide 75681677 by 21.

On to step 1:
21 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 21

Going ahead to step 2:
If we divide 75 by 21, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 63 from 75 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 21

On to step 3:
The number 21 fits into 126 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
The remainder is 0 after subtracting 126 from 126.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 21

On to step 4:
8 divided by 21 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 360.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 21

Advancing to step 5:
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: 3603.0
If we subtract 63 from 81, we get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 21

Going ahead to step 6:
The number 21 fits into 186 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 36038.0
If we subtract 168 from 186, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 21

On to step 7:
21 goes into 187 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 360388.0
Subtract 168 from 187 to get 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 21

Advancing to step 8:
21 can be fit into 197 9 times, resulting in a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 3603889.0
If we subtract 189 from 197, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
80 divided by 21 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 3603889.3
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 3603889.38
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3603889.38
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 3603889.3809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3603889.38095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 3603889.380952
Subtracting 42 from 50 leaves us 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.

Advancing to step 15:
80 divided by 21 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3603889.3809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 16:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 3603889.38095238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 3603889.38095238 with a balance of 2e-09.
