We divide 21214102 by 670
We want to divide 21214102 by 670.

Going ahead to step 1:
670 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 670

Step 2:
21 divided by 670 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 670

Going ahead to step 3:
670 goes into 212 0 times with a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Bring next digit (1) of the dividend behind the 212 and repeat the process: 2121 / 670

On to step 4:
670 can be fit into 2121 3 times, resulting in a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2010 from 2121 leaves us with 111.
Fetch the next digit (4) from the dividend, attach it to 111 and continue: 1114 / 670

Moving on to step 5:
When dividing 1114 by 670, we get 1 with a remainder of 444.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 670 from 1114 and we're left with 444.
Take the next digit (1) from the dividend and append it to 444, then repeat: 4441 / 670

Moving on to step 6:
670 can be fit into 4441 6 times, resulting in a remainder of 421.
Record the quotient 6 as the next digit in the result. 
Result so far: 316.0
If we take 4020 away from 4441, we end up with 421.
Grab the next digit (0) from the dividend, add it to 421, then carry on: 4210 / 670

Step 7:
670 goes into 4210 6 times with a remainder of 190.
Write down 6 as next digit of the result. 
Result so far: 3166.0
Subtract 4020 from 4210 to get 190.
Include the next digit (2) from the dividend after 190, then repeat: 1902 / 670

Advancing to step 8:
When dividing 1902 by 670, we get 2 with a remainder of 562.
Use 2 as the next digit of our solution. 
Result so far: 31662.0
Deduct 1340 from 1902 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 9:
670 can be fit into 5620 8 times, resulting in a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 31662.8
If we take 5360 away from 5620, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 10:
2600 divided by 670 is 3 with a remainder of 590.
Put 3 as the next digit of the answer. 
Result so far: 31662.83
Deduct 2010 from 2600 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 11:
670 goes into 5900 8 times with a remainder of 540.
Put 8 as the next digit of the answer. 
Result so far: 31662.838
The remainder is 540 after subtracting 5360 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 12:
If we divide 5400 by 670, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 31662.8388
Subtract 5360 from 5400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 31662.8388 with a balance of 0.0004.
