We divide 35949429 by 21
We're looking to find how many times 21 goes into 35949429.

Moving on to step 1:
21 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 21

Moving on to step 2:
21 can be fit into 35 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 21 from 35 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 21

Step 3:
21 goes into 149 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 147 from 149 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 21

Going ahead to step 4:
21 can be fit into 24 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
The remainder is 3 after subtracting 21 from 24.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 21

Advancing to step 5:
21 can be fit into 39 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1711.0
Deduct 21 from 39 and we're left with 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 21

Let's proceed to step 6:
The number 21 fits into 184 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 17118.0
Subtracting 168 from 184 leaves us with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 21

Let's proceed to step 7:
The number 21 fits into 162 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 171187.0
If we subtract 147 from 162, we get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 21

Advancing to step 8:
159 divided by 21 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 1711877.0
If we take 147 away from 159, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
21 goes into 120 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1711877.5
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1711877.57
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
If we divide 30 by 21, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 1711877.571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
90 divided by 21 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1711877.5714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1711877.57142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 1711877.571428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 15:
When dividing 120 by 21, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1711877.5714285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 16:
When dividing 150 by 21, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 1711877.57142857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 1711877.57142857 with a balance of 3e-09.
