87204281 ÷ 601 
The aim is to understand the frequency of 601 in 87204281.

Advancing to step 1:
The number 601 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 601

Moving on to step 2:
601 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (2) from the dividend, add it to 87, then carry on: 872 / 601

On to step 3:
601 goes into 872 1 times with a remainder of 271.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 601 away from 872, we end up with 271.
Bring next digit (0) of the dividend behind the 271 and repeat the process: 2710 / 601

Moving on to step 4:
601 can be fit into 2710 4 times, resulting in a remainder of 306.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2404 from 2710 and we're left with 306.
Append the next digit (4) from the dividend to 306 and continue with: 3064 / 601

On to step 5:
The number 601 fits into 3064 5 times, leaving a remainder of 59.
The next digit of our result is 5. 
Result so far: 145.0
Subtract 3005 from 3064 to get 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 601

Let's proceed to step 6:
If we divide 592 by 601, we get 0 and a remainder of 592.
Record the quotient 0 as the next digit in the result. 
Result so far: 1450.0
Subtract 0 from 592 to get 592.
Grab the next digit (8) from the dividend, add it to 592, then carry on: 5928 / 601

Moving on to step 7:
The number 601 fits into 5928 9 times, leaving a remainder of 519.
Use 9 as the next digit of our solution. 
Result so far: 14509.0
Subtract 5409 from 5928 to get 519.
Append the next digit (1) from the dividend to 519 and continue with: 5191 / 601

Advancing to step 8:
If we divide 5191 by 601, we get 8 and a remainder of 383.
Use 8 as the next digit of our solution. 
Result so far: 145098.0
Deduct 4808 from 5191 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Moving on to step 9:
601 can be fit into 3830 6 times, resulting in a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 145098.6
If we subtract 3606 from 3830, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 10:
2240 divided by 601 is 3 with a remainder of 437.
Write down 3 as next digit of the result. 
Result so far: 145098.63
The remainder is 437 after subtracting 1803 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 11:
601 goes into 4370 7 times with a remainder of 163.
The next digit of our result is 7. 
Result so far: 145098.637
If we take 4207 away from 4370, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 12:
The number 601 fits into 1630 2 times, leaving a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 145098.6372
If we take 1202 away from 1630, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 13:
4280 divided by 601 is 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 145098.63727
If we take 4207 away from 4280, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 14:
The number 601 fits into 730 1 times, leaving a remainder of 129.
Record the quotient 1 as the next digit in the result. 
Result so far: 145098.637271
Deduct 601 from 730 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 15:
When dividing 1290 by 601, we get 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 145098.6372712
Deduct 1202 from 1290 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 16:
601 goes into 880 1 times with a remainder of 279.
Put 1 as the next digit of the answer. 
Result so far: 145098.63727121
Deduct 601 from 880 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

The quotient of the division is 145098.63727121, and the remainder is 2.79e-07.
