28297421 ÷ 971 
We want to figure out the number of times 28297421 can be divided by 971.

On to step 1:
When dividing 2 by 971, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 971

On to step 2:
When dividing 28 by 971, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 971

Going ahead to step 3:
When dividing 282 by 971, we get 0 with a remainder of 282.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 282 to get 282.
Append the next digit (9) from the dividend to 282 and continue with: 2829 / 971

Moving on to step 4:
971 goes into 2829 2 times with a remainder of 887.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1942 from 2829 leaves us with 887.
Append the next digit (7) from the dividend to 887 and continue with: 8877 / 971

Step 5:
8877 divided by 971 is 9 with a remainder of 138.
The next digit of our result is 9. 
Result so far: 29.0
If we take 8739 away from 8877, we end up with 138.
Include the next digit (4) from the dividend after 138, then repeat: 1384 / 971

Moving on to step 6:
1384 divided by 971 is 1 with a remainder of 413.
Put 1 as the next digit of the answer. 
Result so far: 291.0
Deduct 971 from 1384 and we're left with 413.
Append the next digit (2) from the dividend to 413 and continue with: 4132 / 971

Advancing to step 7:
When dividing 4132 by 971, we get 4 with a remainder of 248.
Use 4 as the next digit of our solution. 
Result so far: 2914.0
Deduct 3884 from 4132 and we're left with 248.
Include the next digit (1) from the dividend after 248, then repeat: 2481 / 971

Moving on to step 8:
The number 971 fits into 2481 2 times, leaving a remainder of 539.
Put 2 as the next digit of the answer. 
Result so far: 29142.0
If we take 1942 away from 2481, we end up with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Let's proceed to step 9:
When dividing 5390 by 971, we get 5 with a remainder of 535.
Write down 5 as next digit of the result. 
Result so far: 29142.5
If we take 4855 away from 5390, we end up with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Going ahead to step 10:
When dividing 5350 by 971, we get 5 with a remainder of 495.
Put 5 as the next digit of the answer. 
Result so far: 29142.55
Subtracting 4855 from 5350 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

The final result is 29142.55 with a remainder of 0.495.
