We're dividing 91867788 by 601 
The aim is to understand the frequency of 601 in 91867788.

Going ahead to step 1:
601 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 601

Going ahead to step 2:
601 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Take the next digit (8) from the dividend and append it to 91, then repeat: 918 / 601

Advancing to step 3:
918 divided by 601 is 1 with a remainder of 317.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 317 after subtracting 601 from 918.
Include the next digit (6) from the dividend after 317, then repeat: 3176 / 601

On to step 4:
601 can be fit into 3176 5 times, resulting in a remainder of 171.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 171 after subtracting 3005 from 3176.
Include the next digit (7) from the dividend after 171, then repeat: 1717 / 601

Step 5:
The number 601 fits into 1717 2 times, leaving a remainder of 515.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
If we take 1202 away from 1717, we end up with 515.
Fetch the next digit (7) from the dividend, attach it to 515 and continue: 5157 / 601

Let's proceed to step 6:
5157 divided by 601 is 8 with a remainder of 349.
Write down 8 as next digit of the result. 
Result so far: 1528.0
If we take 4808 away from 5157, we end up with 349.
Bring next digit (8) of the dividend behind the 349 and repeat the process: 3498 / 601

Advancing to step 7:
When dividing 3498 by 601, we get 5 with a remainder of 493.
Put 5 as the next digit of the answer. 
Result so far: 15285.0
Subtract 3005 from 3498 to get 493.
Fetch the next digit (8) from the dividend, attach it to 493 and continue: 4938 / 601

Advancing to step 8:
When dividing 4938 by 601, we get 8 with a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 152858.0
The remainder is 130 after subtracting 4808 from 4938.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 9:
If we divide 1300 by 601, we get 2 and a remainder of 98.
Put 2 as the next digit of the answer. 
Result so far: 152858.2
Subtracting 1202 from 1300 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 10:
980 divided by 601 is 1 with a remainder of 379.
The number 1 becomes the next digit in our result. 
Result so far: 152858.21
Deduct 601 from 980 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Step 11:
When dividing 3790 by 601, we get 6 with a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 152858.216
Deduct 3606 from 3790 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 12:
601 goes into 1840 3 times with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 152858.2163
The remainder is 37 after subtracting 1803 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 13:
601 can be fit into 370 0 times, resulting in a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 152858.2163
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 14:
601 goes into 3700 6 times with a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 152858.216306
The remainder is 94 after subtracting 3606 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 15:
601 goes into 940 1 times with a remainder of 339.
Record the quotient 1 as the next digit in the result. 
Result so far: 152858.2163061
Subtract 601 from 940 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Let's proceed to step 16:
The number 601 fits into 3390 5 times, leaving a remainder of 385.
The next digit of our result is 5. 
Result so far: 152858.21630615
Subtract 3005 from 3390 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

The final outcome is 152858.21630615, with a leftover of 3.85e-07.
