21249474 ÷ 283 
We want to figure out the number of times 21249474 can be divided by 283.

Advancing to step 1:
When dividing 2 by 283, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 283

Step 2:
283 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 283

Moving on to step 3:
283 can be fit into 212 0 times, resulting in a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Grab the next digit (4) from the dividend, add it to 212, then carry on: 2124 / 283

Moving on to step 4:
When dividing 2124 by 283, we get 7 with a remainder of 143.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 143 after subtracting 1981 from 2124.
Take the next digit (9) from the dividend and append it to 143, then repeat: 1439 / 283

Going ahead to step 5:
283 can be fit into 1439 5 times, resulting in a remainder of 24.
The next digit of our result is 5. 
Result so far: 75.0
If we take 1415 away from 1439, we end up with 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 283

Let's proceed to step 6:
244 divided by 283 is 0 with a remainder of 244.
The next digit of our result is 0. 
Result so far: 750.0
Subtracting 0 from 244 leaves us with 244.
Grab the next digit (7) from the dividend, add it to 244, then carry on: 2447 / 283

Advancing to step 7:
The number 283 fits into 2447 8 times, leaving a remainder of 183.
Write down 8 as next digit of the result. 
Result so far: 7508.0
The remainder is 183 after subtracting 2264 from 2447.
Fetch the next digit (4) from the dividend, attach it to 183 and continue: 1834 / 283

Step 8:
The number 283 fits into 1834 6 times, leaving a remainder of 136.
The next digit of our result is 6. 
Result so far: 75086.0
The remainder is 136 after subtracting 1698 from 1834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 9:
1360 divided by 283 is 4 with a remainder of 228.
Use 4 as the next digit of our solution. 
Result so far: 75086.4
Subtract 1132 from 1360 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 10:
When dividing 2280 by 283, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 75086.48
Deduct 2264 from 2280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
160 divided by 283 is 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 75086.48
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
283 goes into 1600 5 times with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 75086.4805
Subtracting 1415 from 1600 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 13:
If we divide 1850 by 283, we get 6 and a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 75086.48056
Deduct 1698 from 1850 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 14:
If we divide 1520 by 283, we get 5 and a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 75086.480565
Subtracting 1415 from 1520 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 15:
283 goes into 1050 3 times with a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 75086.4805653
Subtracting 849 from 1050 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 16:
2010 divided by 283 is 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 75086.48056537
The remainder is 29 after subtracting 1981 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 75086.48056537 with a balance of 2.9e-08.
