21189748 ÷ 760 
We want to figure out the number of times 21189748 can be divided by 760.

On to step 1:
2 divided by 760 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 760

Let's proceed to step 2:
When dividing 21 by 760, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 760

Step 3:
When dividing 211 by 760, we get 0 with a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 211 after subtracting 0 from 211.
Include the next digit (8) from the dividend after 211, then repeat: 2118 / 760

Going ahead to step 4:
760 goes into 2118 2 times with a remainder of 598.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 598 after subtracting 1520 from 2118.
Grab the next digit (9) from the dividend, add it to 598, then carry on: 5989 / 760

Going ahead to step 5:
760 goes into 5989 7 times with a remainder of 669.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 669 after subtracting 5320 from 5989.
Fetch the next digit (7) from the dividend, attach it to 669 and continue: 6697 / 760

Let's proceed to step 6:
When dividing 6697 by 760, we get 8 with a remainder of 617.
Write down 8 as next digit of the result. 
Result so far: 278.0
Deduct 6080 from 6697 and we're left with 617.
Grab the next digit (4) from the dividend, add it to 617, then carry on: 6174 / 760

Step 7:
When dividing 6174 by 760, we get 8 with a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 2788.0
If we subtract 6080 from 6174, we get 94.
Take the next digit (8) from the dividend and append it to 94, then repeat: 948 / 760

Moving on to step 8:
The number 760 fits into 948 1 times, leaving a remainder of 188.
Write down 1 as next digit of the result. 
Result so far: 27881.0
Deduct 760 from 948 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 9:
When dividing 1880 by 760, we get 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 27881.2
Subtract 1520 from 1880 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 10:
760 can be fit into 3600 4 times, resulting in a remainder of 560.
Record the quotient 4 as the next digit in the result. 
Result so far: 27881.24
Subtract 3040 from 3600 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 11:
5600 divided by 760 is 7 with a remainder of 280.
Record the quotient 7 as the next digit in the result. 
Result so far: 27881.247
Subtract 5320 from 5600 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
760 goes into 2800 3 times with a remainder of 520.
The next digit of our result is 3. 
Result so far: 27881.2473
If we subtract 2280 from 2800, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 13:
5200 divided by 760 is 6 with a remainder of 640.
The next digit of our result is 6. 
Result so far: 27881.24736
If we subtract 4560 from 5200, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 14:
If we divide 6400 by 760, we get 8 and a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 27881.247368
Subtract 6080 from 6400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
If we divide 3200 by 760, we get 4 and a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 27881.2473684
If we subtract 3040 from 3200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
760 goes into 1600 2 times with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 27881.24736842
If we take 1520 away from 1600, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 27881.24736842, with a leftover of 8e-08.
