16696584 ÷ 253 
The aim is to understand the frequency of 253 in 16696584.

On to step 1:
253 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 253

On to step 2:
253 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 253

On to step 3:
When dividing 166 by 253, we get 0 with a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 166 after subtracting 0 from 166.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 253

Advancing to step 4:
If we divide 1669 by 253, we get 6 and a remainder of 151.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 1518 from 1669 leaves us with 151.
Bring next digit (6) of the dividend behind the 151 and repeat the process: 1516 / 253

Let's proceed to step 5:
When dividing 1516 by 253, we get 5 with a remainder of 251.
The next digit of our result is 5. 
Result so far: 65.0
The remainder is 251 after subtracting 1265 from 1516.
Bring next digit (5) of the dividend behind the 251 and repeat the process: 2515 / 253

Moving on to step 6:
The number 253 fits into 2515 9 times, leaving a remainder of 238.
Use 9 as the next digit of our solution. 
Result so far: 659.0
The remainder is 238 after subtracting 2277 from 2515.
Bring next digit (8) of the dividend behind the 238 and repeat the process: 2388 / 253

Advancing to step 7:
253 goes into 2388 9 times with a remainder of 111.
Use 9 as the next digit of our solution. 
Result so far: 6599.0
Subtract 2277 from 2388 to get 111.
Fetch the next digit (4) from the dividend, attach it to 111 and continue: 1114 / 253

Going ahead to step 8:
253 goes into 1114 4 times with a remainder of 102.
Use 4 as the next digit of our solution. 
Result so far: 65994.0
Subtracting 1012 from 1114 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 9:
253 can be fit into 1020 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 65994.4
If we subtract 1012 from 1020, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 253, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 65994.4
Deduct 0 from 80 and we're left 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.

Step 11:
When dividing 800 by 253, we get 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 65994.403
Deduct 759 from 800 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 12:
The number 253 fits into 410 1 times, leaving a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 65994.4031
The remainder is 157 after subtracting 253 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 13:
If we divide 1570 by 253, we get 6 and a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 65994.40316
The remainder is 52 after subtracting 1518 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
If we divide 520 by 253, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 65994.403162
The remainder is 14 after subtracting 506 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
When dividing 140 by 253, we get 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 65994.403162
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 16:
If we divide 1400 by 253, we get 5 and a remainder of 135.
The next digit of our result is 5. 
Result so far: 65994.40316205
If we take 1265 away from 1400, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The quotient of the division is 65994.40316205, and the remainder is 1.35e-07.
