71049463 divided by 601 
The aim is to understand the frequency of 601 in 71049463.

On to step 1:
If we divide 7 by 601, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 601

On to step 2:
If we divide 71 by 601, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 601

Advancing to step 3:
601 goes into 710 1 times with a remainder of 109.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 601 from 710 and we're left with 109.
Include the next digit (4) from the dividend after 109, then repeat: 1094 / 601

On to step 4:
601 goes into 1094 1 times with a remainder of 493.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 601 from 1094, we get 493.
Append the next digit (9) from the dividend to 493 and continue with: 4939 / 601

Advancing to step 5:
4939 divided by 601 is 8 with a remainder of 131.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Deduct 4808 from 4939 and we're left with 131.
Grab the next digit (4) from the dividend, add it to 131, then carry on: 1314 / 601

On to step 6:
601 goes into 1314 2 times with a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 1182.0
Subtract 1202 from 1314 to get 112.
Grab the next digit (6) from the dividend, add it to 112, then carry on: 1126 / 601

Going ahead to step 7:
If we divide 1126 by 601, we get 1 and a remainder of 525.
Write down 1 as next digit of the result. 
Result so far: 11821.0
The remainder is 525 after subtracting 601 from 1126.
Take the next digit (3) from the dividend and append it to 525, then repeat: 5253 / 601

Moving on to step 8:
601 can be fit into 5253 8 times, resulting in a remainder of 445.
The next digit of our result is 8. 
Result so far: 118218.0
If we subtract 4808 from 5253, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 9:
When dividing 4450 by 601, we get 7 with a remainder of 243.
Put 7 as the next digit of the answer. 
Result so far: 118218.7
Subtracting 4207 from 4450 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Moving on to step 10:
601 goes into 2430 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 118218.74
If we subtract 2404 from 2430, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
When dividing 260 by 601, we get 0 with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 118218.74
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
If we divide 2600 by 601, we get 4 and a remainder of 196.
Record the quotient 4 as the next digit in the result. 
Result so far: 118218.7404
Subtracting 2404 from 2600 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 13:
601 can be fit into 1960 3 times, resulting in a remainder of 157.
Put 3 as the next digit of the answer. 
Result so far: 118218.74043
Subtract 1803 from 1960 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 14:
601 can be fit into 1570 2 times, resulting in a remainder of 368.
Write down 2 as next digit of the result. 
Result so far: 118218.740432
Subtract 1202 from 1570 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 15:
If we divide 3680 by 601, we get 6 and a remainder of 74.
The next digit of our result is 6. 
Result so far: 118218.7404326
Subtract 3606 from 3680 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 16:
740 divided by 601 is 1 with a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 118218.74043261
Subtracting 601 from 740 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

The final outcome is 118218.74043261, with a leftover of 1.39e-07.
