29386904 divided by 21 
We want to divide 29386904 by 21.

Advancing to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 21

On to step 2:
21 can be fit into 29 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 8 after subtracting 21 from 29.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 21

Advancing to step 3:
21 goes into 83 3 times with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 63 from 83 leaves us with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 21

Moving on to step 4:
The number 21 fits into 208 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Deduct 189 from 208 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 5:
21 can be fit into 196 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1399.0
If we subtract 189 from 196, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 21

Let's proceed to step 6:
The number 21 fits into 79 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 13993.0
Subtract 63 from 79 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 21

Moving on to step 7:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 139937.0
Deduct 147 from 160 and we're left with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 21

On to step 8:
The number 21 fits into 134 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1399376.0
Subtract 126 from 134 to 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.

Going ahead to step 9:
80 divided by 21 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 1399376.3
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
170 divided by 21 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1399376.38
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.

Moving on to step 11:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1399376.38
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
200 divided by 21 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 1399376.3809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1399376.38095
Subtracting 105 from 110 leaves us 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.

Let's proceed to step 14:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1399376.380952
Subtract 42 from 50 to 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 15:
21 goes into 80 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 1399376.3809523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 16:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1399376.38095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 1399376.38095238, and the remainder is 2e-09.
