277189 ÷ 21 
Our goal is to divide 277189 by 21.

Advancing to step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 21

Going ahead to step 2:
21 can be fit into 27 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 21 from 27, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 21

Let's proceed to step 3:
The number 21 fits into 67 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 63 from 67, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 21

Advancing to step 4:
21 goes into 41 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtracting 21 from 41 leaves us with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 21

Advancing to step 5:
If we divide 208 by 21, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 1319.0
Subtracting 189 from 208 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 21

Advancing to step 6:
The number 21 fits into 199 9 times, leaving a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 13199.0
Subtracting 189 from 199 leaves us 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.

On to step 7:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 13199.4
Deduct 84 from 100 and we're left 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.

Moving on to step 8:
21 goes into 160 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 13199.47
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
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: 13199.476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
21 goes into 40 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 13199.4761
Subtract 21 from 40 to 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.

Going ahead to step 11:
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: 13199.47619
Deduct 189 from 190 and we're left 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 12:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13199.47619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 13199.4761904
If we subtract 84 from 100, we get 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 14:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 13199.47619047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 13199.47619047, and the remainder is 1.3e-08.
