We look at the division of 21521229 by 890 
We want to divide 21521229 by 890.

Going ahead to step 1:
2 divided by 890 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 890

On to step 2:
890 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 890

Let's proceed to step 3:
890 goes into 215 0 times with a remainder of 215.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 215 after subtracting 0 from 215.
Grab the next digit (2) from the dividend, add it to 215, then carry on: 2152 / 890

Advancing to step 4:
2152 divided by 890 is 2 with a remainder of 372.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1780 from 2152 to get 372.
Take the next digit (1) from the dividend and append it to 372, then repeat: 3721 / 890

Going ahead to step 5:
When dividing 3721 by 890, we get 4 with a remainder of 161.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 3560 from 3721 and we're left with 161.
Include the next digit (2) from the dividend after 161, then repeat: 1612 / 890

Going ahead to step 6:
1612 divided by 890 is 1 with a remainder of 722.
Write down 1 as next digit of the result. 
Result so far: 241.0
If we subtract 890 from 1612, we get 722.
Include the next digit (2) from the dividend after 722, then repeat: 7222 / 890

Going ahead to step 7:
The number 890 fits into 7222 8 times, leaving a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 2418.0
Subtract 7120 from 7222 to get 102.
Append the next digit (9) from the dividend to 102 and continue with: 1029 / 890

Moving on to step 8:
When dividing 1029 by 890, we get 1 with a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 24181.0
The remainder is 139 after subtracting 890 from 1029.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 9:
1390 divided by 890 is 1 with a remainder of 500.
Write down 1 as next digit of the result. 
Result so far: 24181.1
If we subtract 890 from 1390, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 10:
890 can be fit into 5000 5 times, resulting in a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 24181.15
Deduct 4450 from 5000 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 11:
If we divide 5500 by 890, we get 6 and a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 24181.156
If we subtract 5340 from 5500, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
1600 divided by 890 is 1 with a remainder of 710.
Put 1 as the next digit of the answer. 
Result so far: 24181.1561
Subtract 890 from 1600 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 13:
890 can be fit into 7100 7 times, resulting in a remainder of 870.
Record the quotient 7 as the next digit in the result. 
Result so far: 24181.15617
Subtract 6230 from 7100 to get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

On to step 14:
890 can be fit into 8700 9 times, resulting in a remainder of 690.
Record the quotient 9 as the next digit in the result. 
Result so far: 24181.156179
The remainder is 690 after subtracting 8010 from 8700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 15:
890 can be fit into 6900 7 times, resulting in a remainder of 670.
Write down 7 as next digit of the result. 
Result so far: 24181.1561797
If we subtract 6230 from 6900, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Advancing to step 16:
When dividing 6700 by 890, we get 7 with a remainder of 470.
Put 7 as the next digit of the answer. 
Result so far: 24181.15617977
If we take 6230 away from 6700, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The quotient of the division is 24181.15617977, and the remainder is 4.7e-07.
