36861006 ÷ 253 
The aim is to understand the frequency of 253 in 36861006.

Moving on to step 1:
3 divided by 253 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 253

Moving on to step 2:
36 divided by 253 is 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 253

Moving on to step 3:
368 divided by 253 is 1 with a remainder of 115.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 253 from 368, we get 115.
Fetch the next digit (6) from the dividend, attach it to 115 and continue: 1156 / 253

Let's proceed to step 4:
1156 divided by 253 is 4 with a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 1012 away from 1156, we end up with 144.
Fetch the next digit (1) from the dividend, attach it to 144 and continue: 1441 / 253

Let's proceed to step 5:
253 goes into 1441 5 times with a remainder of 176.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
The remainder is 176 after subtracting 1265 from 1441.
Bring next digit (0) of the dividend behind the 176 and repeat the process: 1760 / 253

Advancing to step 6:
1760 divided by 253 is 6 with a remainder of 242.
The next digit of our result is 6. 
Result so far: 1456.0
Subtracting 1518 from 1760 leaves us with 242.
Include the next digit (0) from the dividend after 242, then repeat: 2420 / 253

Moving on to step 7:
2420 divided by 253 is 9 with a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 14569.0
If we take 2277 away from 2420, we end up with 143.
Append the next digit (6) from the dividend to 143 and continue with: 1436 / 253

On to step 8:
The number 253 fits into 1436 5 times, leaving a remainder of 171.
Record the quotient 5 as the next digit in the result. 
Result so far: 145695.0
Subtracting 1265 from 1436 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 9:
1710 divided by 253 is 6 with a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 145695.6
Subtract 1518 from 1710 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 10:
If we divide 1920 by 253, we get 7 and a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 145695.67
The remainder is 149 after subtracting 1771 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 11:
If we divide 1490 by 253, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 145695.675
If we subtract 1265 from 1490, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 12:
The number 253 fits into 2250 8 times, leaving a remainder of 226.
Put 8 as the next digit of the answer. 
Result so far: 145695.6758
If we subtract 2024 from 2250, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 13:
2260 divided by 253 is 8 with a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 145695.67588
Subtracting 2024 from 2260 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The quotient of the division is 145695.67588, and the remainder is 0.000236.
