We look at the division of 21321270 by 346 
We're looking to find how many times 346 goes into 21321270.

Moving on to step 1:
The number 346 fits into 2 0 times, leaving 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 346

Moving on to step 2:
346 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 346

Going ahead to step 3:
The number 346 fits into 213 0 times, leaving a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 213 to get 213.
Grab the next digit (2) from the dividend, add it to 213, then carry on: 2132 / 346

Moving on to step 4:
346 can be fit into 2132 6 times, resulting in a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 2076 from 2132 and we're left with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 346

Let's proceed to step 5:
346 goes into 561 1 times with a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 346 from 561 to get 215.
Take the next digit (2) from the dividend and append it to 215, then repeat: 2152 / 346

Going ahead to step 6:
If we divide 2152 by 346, we get 6 and a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 616.0
Deduct 2076 from 2152 and we're left with 76.
Append the next digit (7) from the dividend to 76 and continue with: 767 / 346

Moving on to step 7:
The number 346 fits into 767 2 times, leaving a remainder of 75.
Put 2 as the next digit of the answer. 
Result so far: 6162.0
Subtract 692 from 767 to get 75.
Fetch the next digit (0) from the dividend, attach it to 75 and continue: 750 / 346

On to step 8:
When dividing 750 by 346, we get 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 61622.0
Subtracting 692 from 750 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
580 divided by 346 is 1 with a remainder of 234.
The next digit of our result is 1. 
Result so far: 61622.1
The remainder is 234 after subtracting 346 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 10:
346 can be fit into 2340 6 times, resulting in a remainder of 264.
The next digit of our result is 6. 
Result so far: 61622.16
If we subtract 2076 from 2340, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 11:
346 goes into 2640 7 times with a remainder of 218.
The next digit of our result is 7. 
Result so far: 61622.167
If we subtract 2422 from 2640, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 12:
The number 346 fits into 2180 6 times, leaving a remainder of 104.
The next digit of our result is 6. 
Result so far: 61622.1676
Subtracting 2076 from 2180 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 13:
The number 346 fits into 1040 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 61622.16763
If we subtract 1038 from 1040, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
When dividing 20 by 346, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 61622.16763
Deduct 0 from 20 and we're left with 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 15:
200 divided by 346 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 61622.16763
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 61622.16763 with a balance of 2e-06.
