We look at the division of 21821559 by 674 
We're looking to find how many times 674 goes into 21821559.

On to step 1:
674 goes into 2 0 times with 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.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 674

Advancing to step 2:
674 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 674

Going ahead to step 3:
When dividing 218 by 674, we get 0 with a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 218 to get 218.
Append the next digit (2) from the dividend to 218 and continue with: 2182 / 674

Moving on to step 4:
When dividing 2182 by 674, we get 3 with a remainder of 160.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2022 from 2182, we get 160.
Fetch the next digit (1) from the dividend, attach it to 160 and continue: 1601 / 674

Step 5:
674 goes into 1601 2 times with a remainder of 253.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 1348 from 1601, we get 253.
Take the next digit (5) from the dividend and append it to 253, then repeat: 2535 / 674

Step 6:
674 can be fit into 2535 3 times, resulting in a remainder of 513.
The next digit of our result is 3. 
Result so far: 323.0
If we subtract 2022 from 2535, we get 513.
Append the next digit (5) from the dividend to 513 and continue with: 5135 / 674

Going ahead to step 7:
The number 674 fits into 5135 7 times, leaving a remainder of 417.
Put 7 as the next digit of the answer. 
Result so far: 3237.0
Deduct 4718 from 5135 and we're left with 417.
Take the next digit (9) from the dividend and append it to 417, then repeat: 4179 / 674

Moving on to step 8:
4179 divided by 674 is 6 with a remainder of 135.
Put 6 as the next digit of the answer. 
Result so far: 32376.0
Subtract 4044 from 4179 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
674 goes into 1350 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 32376.2
If we subtract 1348 from 1350, 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 10:
When dividing 20 by 674, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 32376.2
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.

Advancing to step 11:
200 divided by 674 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 32376.2
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 32376.2 and a remainder of 0.02.
