23358636 ÷ 601 
The aim is to understand the frequency of 601 in 23358636.

On to step 1:
If we divide 2 by 601, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 601

Step 2:
601 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 601

Advancing to step 3:
601 can be fit into 233 0 times, resulting in a remainder of 233.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 233 to get 233.
Grab the next digit (5) from the dividend, add it to 233, then carry on: 2335 / 601

On to step 4:
601 goes into 2335 3 times with a remainder of 532.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1803 from 2335 and we're left with 532.
Take the next digit (8) from the dividend and append it to 532, then repeat: 5328 / 601

Let's proceed to step 5:
The number 601 fits into 5328 8 times, leaving a remainder of 520.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 4808 from 5328 leaves us with 520.
Append the next digit (6) from the dividend to 520 and continue with: 5206 / 601

Going ahead to step 6:
601 goes into 5206 8 times with a remainder of 398.
The next digit of our result is 8. 
Result so far: 388.0
Deduct 4808 from 5206 and we're left with 398.
Bring next digit (3) of the dividend behind the 398 and repeat the process: 3983 / 601

Going ahead to step 7:
The number 601 fits into 3983 6 times, leaving a remainder of 377.
Use 6 as the next digit of our solution. 
Result so far: 3886.0
The remainder is 377 after subtracting 3606 from 3983.
Take the next digit (6) from the dividend and append it to 377, then repeat: 3776 / 601

Moving on to step 8:
The number 601 fits into 3776 6 times, leaving a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 38866.0
If we subtract 3606 from 3776, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 9:
1700 divided by 601 is 2 with a remainder of 498.
Use 2 as the next digit of our solution. 
Result so far: 38866.2
Subtract 1202 from 1700 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 10:
When dividing 4980 by 601, we get 8 with a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 38866.28
If we subtract 4808 from 4980, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 11:
When dividing 1720 by 601, we get 2 with a remainder of 518.
Record the quotient 2 as the next digit in the result. 
Result so far: 38866.282
Subtracting 1202 from 1720 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 12:
If we divide 5180 by 601, we get 8 and a remainder of 372.
The next digit of our result is 8. 
Result so far: 38866.2828
The remainder is 372 after subtracting 4808 from 5180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 13:
601 can be fit into 3720 6 times, resulting in a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 38866.28286
If we take 3606 away from 3720, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 14:
If we divide 1140 by 601, we get 1 and a remainder of 539.
Record the quotient 1 as the next digit in the result. 
Result so far: 38866.282861
Subtracting 601 from 1140 leaves us with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Let's proceed to step 15:
601 can be fit into 5390 8 times, resulting in a remainder of 582.
Use 8 as the next digit of our solution. 
Result so far: 38866.2828618
Deduct 4808 from 5390 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Going ahead to step 16:
The number 601 fits into 5820 9 times, leaving a remainder of 411.
Put 9 as the next digit of the answer. 
Result so far: 38866.28286189
Subtract 5409 from 5820 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

The quotient of the division is 38866.28286189, and the remainder is 4.11e-07.
