21086831 divided by 197 
We want to figure out the number of times 21086831 can be divided by 197.

On to step 1:
2 divided by 197 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 197

Advancing to step 2:
When dividing 21 by 197, we get 0 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.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 197

Going ahead to step 3:
If we divide 210 by 197, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 197 from 210 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 197

Going ahead to step 4:
197 goes into 138 0 times with a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 138 leaves us with 138.
Fetch the next digit (6) from the dividend, attach it to 138 and continue: 1386 / 197

Step 5:
The number 197 fits into 1386 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we take 1379 away from 1386, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 197

Step 6:
78 divided by 197 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 1070.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 197

Advancing to step 7:
If we divide 783 by 197, we get 3 and a remainder of 192.
Write down 3 as next digit of the result. 
Result so far: 10703.0
If we take 591 away from 783, we end up with 192.
Append the next digit (1) from the dividend to 192 and continue with: 1921 / 197

Let's proceed to step 8:
1921 divided by 197 is 9 with a remainder of 148.
The number 9 becomes the next digit in our result. 
Result so far: 107039.0
If we subtract 1773 from 1921, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 9:
197 goes into 1480 7 times with a remainder of 101.
Write down 7 as next digit of the result. 
Result so far: 107039.7
Deduct 1379 from 1480 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 10:
When dividing 1010 by 197, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 107039.75
Subtracting 985 from 1010 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
250 divided by 197 is 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 107039.751
If we subtract 197 from 250, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
When dividing 530 by 197, we get 2 with a remainder of 136.
The next digit of our result is 2. 
Result so far: 107039.7512
Subtract 394 from 530 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 13:
1360 divided by 197 is 6 with a remainder of 178.
The number 6 becomes the next digit in our result. 
Result so far: 107039.75126
If we subtract 1182 from 1360, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 14:
If we divide 1780 by 197, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 107039.751269
If we take 1773 away from 1780, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 15:
70 divided by 197 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 107039.751269
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 16:
When dividing 700 by 197, we get 3 with a remainder of 109.
The number 3 becomes the next digit in our result. 
Result so far: 107039.75126903
Subtract 591 from 700 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

The final result is 107039.75126903 with a remainder of 1.09e-07.
