Let's divide 70863228 by 601
The aim is to understand the frequency of 601 in 70863228.

On to step 1:
When dividing 7 by 601, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 601

Step 2:
601 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 601

On to step 3:
601 can be fit into 708 1 times, resulting in a remainder of 107.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 601 from 708 and we're left with 107.
Bring next digit (6) of the dividend behind the 107 and repeat the process: 1076 / 601

On to step 4:
The number 601 fits into 1076 1 times, leaving a remainder of 475.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 601 from 1076 and we're left with 475.
Include the next digit (3) from the dividend after 475, then repeat: 4753 / 601

Moving on to step 5:
The number 601 fits into 4753 7 times, leaving a remainder of 546.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Deduct 4207 from 4753 and we're left with 546.
Bring next digit (2) of the dividend behind the 546 and repeat the process: 5462 / 601

On to step 6:
601 goes into 5462 9 times with a remainder of 53.
The next digit of our result is 9. 
Result so far: 1179.0
The remainder is 53 after subtracting 5409 from 5462.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 601

Moving on to step 7:
When dividing 532 by 601, we get 0 with a remainder of 532.
The number 0 becomes the next digit in our result. 
Result so far: 11790.0
The remainder is 532 after subtracting 0 from 532.
Include the next digit (8) from the dividend after 532, then repeat: 5328 / 601

Step 8:
When dividing 5328 by 601, we get 8 with a remainder of 520.
Record the quotient 8 as the next digit in the result. 
Result so far: 117908.0
Deduct 4808 from 5328 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 9:
601 can be fit into 5200 8 times, resulting in a remainder of 392.
Record the quotient 8 as the next digit in the result. 
Result so far: 117908.8
Subtract 4808 from 5200 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 10:
601 can be fit into 3920 6 times, resulting in a remainder of 314.
The number 6 becomes the next digit in our result. 
Result so far: 117908.86
The remainder is 314 after subtracting 3606 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 11:
If we divide 3140 by 601, we get 5 and a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 117908.865
If we take 3005 away from 3140, 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.

Step 12:
601 goes into 1350 2 times with a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 117908.8652
The remainder is 148 after subtracting 1202 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 13:
The number 601 fits into 1480 2 times, leaving a remainder of 278.
Record the quotient 2 as the next digit in the result. 
Result so far: 117908.86522
Deduct 1202 from 1480 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

After the division, we end up with 117908.86522 and a remainder of 0.000278.
