We divide 21428901 by 289
We want to divide 21428901 by 289.

Step 1:
289 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 289

Advancing to step 2:
When dividing 21 by 289, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 289

Let's proceed to step 3:
289 goes into 214 0 times with a remainder of 214.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 214 leaves us with 214.
Append the next digit (2) from the dividend to 214 and continue with: 2142 / 289

Let's proceed to step 4:
289 goes into 2142 7 times with a remainder of 119.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 2023 away from 2142, we end up with 119.
Take the next digit (8) from the dividend and append it to 119, then repeat: 1198 / 289

Advancing to step 5:
1198 divided by 289 is 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we subtract 1156 from 1198, we get 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 289

Let's proceed to step 6:
When dividing 429 by 289, we get 1 with a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 741.0
Subtract 289 from 429 to get 140.
Append the next digit (0) from the dividend to 140 and continue with: 1400 / 289

Advancing to step 7:
The number 289 fits into 1400 4 times, leaving a remainder of 244.
Use 4 as the next digit of our solution. 
Result so far: 7414.0
If we take 1156 away from 1400, we end up with 244.
Grab the next digit (1) from the dividend, add it to 244, then carry on: 2441 / 289

Moving on to step 8:
When dividing 2441 by 289, we get 8 with a remainder of 129.
Use 8 as the next digit of our solution. 
Result so far: 74148.0
Subtract 2312 from 2441 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 9:
289 goes into 1290 4 times with a remainder of 134.
The next digit of our result is 4. 
Result so far: 74148.4
The remainder is 134 after subtracting 1156 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
289 goes into 1340 4 times with a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 74148.44
Deduct 1156 from 1340 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Our division results in 74148.44 with a remaining 0.184.
