Let's divide 21556830 by 74
Our goal is to divide 21556830 by 74.

Step 1:
74 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 74

Step 2:
The number 74 fits into 21 0 times, leaving 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.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 74

Moving on to step 3:
The number 74 fits into 215 2 times, leaving a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 67 after subtracting 148 from 215.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 74

On to step 4:
74 can be fit into 675 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 666 from 675 and we're left with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 74

Step 5:
When dividing 96 by 74, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 291.0
If we subtract 74 from 96, we get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 74

Step 6:
74 can be fit into 228 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 2913.0
Subtract 222 from 228 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 74

Advancing to step 7:
63 divided by 74 is 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 29130.0
Subtracting 0 from 63 leaves us with 63.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 74

Advancing to step 8:
If we divide 630 by 74, we get 8 and a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 291308.0
Subtract 592 from 630 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
If we divide 380 by 74, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 291308.5
If we subtract 370 from 380, we 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:
The number 74 fits into 100 1 times, leaving a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 291308.51
If we subtract 74 from 100, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
The number 74 fits into 260 3 times, leaving a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 291308.513
Subtracting 222 from 260 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
74 goes into 380 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 291308.5135
Subtracting 370 from 380 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
74 can be fit into 100 1 times, resulting in a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 291308.51351
Deduct 74 from 100 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
260 divided by 74 is 3 with a remainder of 38.
The next digit of our result is 3. 
Result so far: 291308.513513
If we take 222 away from 260, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 15:
The number 74 fits into 380 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 291308.5135135
The remainder is 10 after subtracting 370 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
When dividing 100 by 74, we get 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 291308.51351351
Deduct 74 from 100 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 291308.51351351, with a leftover of 2.6e-08.
