We look at the division of 23970188 by 843 
We want to figure out the number of times 23970188 can be divided by 843.

On to step 1:
The number 843 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 843

Going ahead to step 2:
23 divided by 843 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 843

Advancing to step 3:
843 can be fit into 239 0 times, resulting in a remainder of 239.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 239, we get 239.
Take the next digit (7) from the dividend and append it to 239, then repeat: 2397 / 843

Moving on to step 4:
843 goes into 2397 2 times with a remainder of 711.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1686 from 2397 leaves us with 711.
Fetch the next digit (0) from the dividend, attach it to 711 and continue: 7110 / 843

Moving on to step 5:
7110 divided by 843 is 8 with a remainder of 366.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 6744 from 7110 and we're left with 366.
Grab the next digit (1) from the dividend, add it to 366, then carry on: 3661 / 843

On to step 6:
843 goes into 3661 4 times with a remainder of 289.
Put 4 as the next digit of the answer. 
Result so far: 284.0
Subtracting 3372 from 3661 leaves us with 289.
Take the next digit (8) from the dividend and append it to 289, then repeat: 2898 / 843

Moving on to step 7:
843 can be fit into 2898 3 times, resulting in a remainder of 369.
The number 3 becomes the next digit in our result. 
Result so far: 2843.0
Subtracting 2529 from 2898 leaves us with 369.
Fetch the next digit (8) from the dividend, attach it to 369 and continue: 3698 / 843

Going ahead to step 8:
843 can be fit into 3698 4 times, resulting in a remainder of 326.
The number 4 becomes the next digit in our result. 
Result so far: 28434.0
If we subtract 3372 from 3698, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 9:
3260 divided by 843 is 3 with a remainder of 731.
Put 3 as the next digit of the answer. 
Result so far: 28434.3
Subtracting 2529 from 3260 leaves us with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Step 10:
843 goes into 7310 8 times with a remainder of 566.
The next digit of our result is 8. 
Result so far: 28434.38
Subtracting 6744 from 7310 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Advancing to step 11:
843 can be fit into 5660 6 times, resulting in a remainder of 602.
The next digit of our result is 6. 
Result so far: 28434.386
Subtract 5058 from 5660 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 12:
6020 divided by 843 is 7 with a remainder of 119.
Write down 7 as next digit of the result. 
Result so far: 28434.3867
Subtracting 5901 from 6020 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 13:
843 goes into 1190 1 times with a remainder of 347.
The next digit of our result is 1. 
Result so far: 28434.38671
If we subtract 843 from 1190, we get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 14:
The number 843 fits into 3470 4 times, leaving a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 28434.386714
Deduct 3372 from 3470 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 15:
843 goes into 980 1 times with a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 28434.3867141
Subtract 843 from 980 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 16:
If we divide 1370 by 843, we get 1 and a remainder of 527.
Record the quotient 1 as the next digit in the result. 
Result so far: 28434.38671411
If we subtract 843 from 1370, we get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

The final outcome is 28434.38671411, with a leftover of 5.27e-07.
