21666952 divided by 341 
We want to figure out the number of times 21666952 can be divided by 341.

Step 1:
2 divided by 341 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 341

Moving on to step 2:
The number 341 fits into 21 0 times, leaving 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 (6) from the dividend to 21 and continue with: 216 / 341

Let's proceed to step 3:
The number 341 fits into 216 0 times, leaving a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Bring next digit (6) of the dividend behind the 216 and repeat the process: 2166 / 341

Advancing to step 4:
341 goes into 2166 6 times with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 2046 from 2166 and we're left with 120.
Include the next digit (6) from the dividend after 120, then repeat: 1206 / 341

Advancing to step 5:
The number 341 fits into 1206 3 times, leaving a remainder of 183.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 1023 from 1206 leaves us with 183.
Grab the next digit (9) from the dividend, add it to 183, then carry on: 1839 / 341

Let's proceed to step 6:
341 goes into 1839 5 times with a remainder of 134.
Put 5 as the next digit of the answer. 
Result so far: 635.0
If we subtract 1705 from 1839, we get 134.
Grab the next digit (5) from the dividend, add it to 134, then carry on: 1345 / 341

On to step 7:
The number 341 fits into 1345 3 times, leaving a remainder of 322.
Use 3 as the next digit of our solution. 
Result so far: 6353.0
Subtract 1023 from 1345 to get 322.
Include the next digit (2) from the dividend after 322, then repeat: 3222 / 341

Step 8:
If we divide 3222 by 341, we get 9 and a remainder of 153.
Write down 9 as next digit of the result. 
Result so far: 63539.0
Subtract 3069 from 3222 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 9:
341 can be fit into 1530 4 times, resulting in a remainder of 166.
Put 4 as the next digit of the answer. 
Result so far: 63539.4
If we subtract 1364 from 1530, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 10:
1660 divided by 341 is 4 with a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 63539.44
The remainder is 296 after subtracting 1364 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 63539.44 with a remainder of 0.296.
