21408661 ÷ 175 
We want to divide 21408661 by 175.

Let's proceed to step 1:
The number 175 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 175

Going ahead to step 2:
If we divide 21 by 175, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 175

Step 3:
175 goes into 214 1 times with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 175 from 214, we get 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 175

Advancing to step 4:
175 can be fit into 390 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 350 from 390 to get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 175

Step 5:
If we divide 408 by 175, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtracting 350 from 408 leaves us with 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 175

Let's proceed to step 6:
175 goes into 586 3 times with a remainder of 61.
The next digit of our result is 3. 
Result so far: 1223.0
Deduct 525 from 586 and we're left with 61.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 175

On to step 7:
The number 175 fits into 616 3 times, leaving a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 12233.0
If we take 525 away from 616, we end up with 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 175

Let's proceed to step 8:
The number 175 fits into 911 5 times, leaving a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 122335.0
Subtract 875 from 911 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
The number 175 fits into 360 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 122335.2
Subtract 350 from 360 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 175 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 122335.2
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
The number 175 fits into 1000 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 122335.205
If we subtract 875 from 1000, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 12:
175 can be fit into 1250 7 times, resulting in a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 122335.2057
Subtract 1225 from 1250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
175 goes into 250 1 times with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 122335.20571
The remainder is 75 after subtracting 175 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
175 can be fit into 750 4 times, resulting in a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 122335.205714
If we subtract 700 from 750, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 15:
500 divided by 175 is 2 with a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 122335.2057142
If we take 350 away from 500, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 16:
If we divide 1500 by 175, we get 8 and a remainder of 100.
The next digit of our result is 8. 
Result so far: 122335.20571428
The remainder is 100 after subtracting 1400 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 122335.20571428 with a balance of 1e-07.
