We divide 21408186 by 763
The aim is to understand the frequency of 763 in 21408186.

Advancing to step 1:
When dividing 2 by 763, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 763

Step 2:
The number 763 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 763

Step 3:
763 goes into 214 0 times with a remainder of 214.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 214 after subtracting 0 from 214.
Include the next digit (0) from the dividend after 214, then repeat: 2140 / 763

Going ahead to step 4:
763 goes into 2140 2 times with a remainder of 614.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1526 from 2140 and we're left with 614.
Grab the next digit (8) from the dividend, add it to 614, then carry on: 6148 / 763

Step 5:
763 goes into 6148 8 times with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 6104 away from 6148, we end up with 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 763

Let's proceed to step 6:
When dividing 441 by 763, we get 0 with a remainder of 441.
Put 0 as the next digit of the answer. 
Result so far: 280.0
Deduct 0 from 441 and we're left with 441.
Grab the next digit (8) from the dividend, add it to 441, then carry on: 4418 / 763

Moving on to step 7:
4418 divided by 763 is 5 with a remainder of 603.
Use 5 as the next digit of our solution. 
Result so far: 2805.0
Subtract 3815 from 4418 to get 603.
Take the next digit (6) from the dividend and append it to 603, then repeat: 6036 / 763

Advancing to step 8:
763 can be fit into 6036 7 times, resulting in a remainder of 695.
Write down 7 as next digit of the result. 
Result so far: 28057.0
Deduct 5341 from 6036 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Advancing to step 9:
763 goes into 6950 9 times with a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 28057.9
If we subtract 6867 from 6950, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 10:
763 goes into 830 1 times with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 28057.91
If we take 763 away from 830, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 11:
763 goes into 670 0 times with a remainder of 670.
The next digit of our result is 0. 
Result so far: 28057.91
If we take 0 away from 670, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Advancing to step 12:
763 goes into 6700 8 times with a remainder of 596.
Record the quotient 8 as the next digit in the result. 
Result so far: 28057.9108
Subtracting 6104 from 6700 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Going ahead to step 13:
763 can be fit into 5960 7 times, resulting in a remainder of 619.
The next digit of our result is 7. 
Result so far: 28057.91087
If we take 5341 away from 5960, we end up with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Advancing to step 14:
763 can be fit into 6190 8 times, resulting in a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 28057.910878
Subtracting 6104 from 6190 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 15:
If we divide 860 by 763, we get 1 and a remainder of 97.
Use 1 as the next digit of our solution. 
Result so far: 28057.9108781
Subtract 763 from 860 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 16:
If we divide 970 by 763, we get 1 and a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 28057.91087811
Subtracting 763 from 970 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

After the division, we end up with 28057.91087811 and a remainder of 2.07e-07.
