We divide 21403831 by 670
We're looking to find how many times 670 goes into 21403831.

Step 1:
When dividing 2 by 670, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 670

Let's proceed to step 2:
670 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 670

Going ahead to step 3:
When dividing 214 by 670, we get 0 with a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Take the next digit (0) from the dividend and append it to 214, then repeat: 2140 / 670

Step 4:
The number 670 fits into 2140 3 times, leaving a remainder of 130.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2010 away from 2140, we end up with 130.
Include the next digit (3) from the dividend after 130, then repeat: 1303 / 670

Step 5:
When dividing 1303 by 670, we get 1 with a remainder of 633.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 670 from 1303 to get 633.
Append the next digit (8) from the dividend to 633 and continue with: 6338 / 670

On to step 6:
6338 divided by 670 is 9 with a remainder of 308.
The next digit of our result is 9. 
Result so far: 319.0
If we take 6030 away from 6338, we end up with 308.
Append the next digit (3) from the dividend to 308 and continue with: 3083 / 670

Going ahead to step 7:
When dividing 3083 by 670, we get 4 with a remainder of 403.
Write down 4 as next digit of the result. 
Result so far: 3194.0
Subtracting 2680 from 3083 leaves us with 403.
Take the next digit (1) from the dividend and append it to 403, then repeat: 4031 / 670

Advancing to step 8:
670 goes into 4031 6 times with a remainder of 11.
The next digit of our result is 6. 
Result so far: 31946.0
Subtract 4020 from 4031 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
110 divided by 670 is 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 31946.0
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
If we divide 1100 by 670, we get 1 and a remainder of 430.
The next digit of our result is 1. 
Result so far: 31946.01
If we take 670 away from 1100, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 11:
670 goes into 4300 6 times with a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 31946.016
If we subtract 4020 from 4300, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
670 can be fit into 2800 4 times, resulting in a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 31946.0164
If we take 2680 away from 2800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
When dividing 1200 by 670, we get 1 with a remainder of 530.
Record the quotient 1 as the next digit in the result. 
Result so far: 31946.01641
The remainder is 530 after subtracting 670 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 14:
The number 670 fits into 5300 7 times, leaving a remainder of 610.
Write down 7 as next digit of the result. 
Result so far: 31946.016417
Subtracting 4690 from 5300 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 15:
The number 670 fits into 6100 9 times, leaving a remainder of 70.
The next digit of our result is 9. 
Result so far: 31946.0164179
If we take 6030 away from 6100, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 16:
If we divide 700 by 670, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 31946.01641791
If we subtract 670 from 700, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 31946.01641791, with a leftover of 3e-08.
