We divide 43215951 by 201
The aim is to understand the frequency of 201 in 43215951.

Step 1:
4 divided by 201 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 201

Moving on to step 2:
201 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 201

Let's proceed to step 3:
201 can be fit into 432 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 30 after subtracting 402 from 432.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 201

Let's proceed to step 4:
201 goes into 301 1 times with a remainder of 100.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 100 after subtracting 201 from 301.
Include the next digit (5) from the dividend after 100, then repeat: 1005 / 201

Going ahead to step 5:
201 can be fit into 1005 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 215.0
Subtract 1005 from 1005 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 201

On to step 6:
9 divided by 201 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 2150.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 201

Going ahead to step 7:
95 divided by 201 is 0 with a remainder of 95.
Record the quotient 0 as the next digit in the result. 
Result so far: 21500.0
Subtract 0 from 95 to get 95.
Fetch the next digit (1) from the dividend, attach it to 95 and continue: 951 / 201

Step 8:
When dividing 951 by 201, we get 4 with a remainder of 147.
Write down 4 as next digit of the result. 
Result so far: 215004.0
If we subtract 804 from 951, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
The number 201 fits into 1470 7 times, leaving a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 215004.7
If we take 1407 away from 1470, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 10:
630 divided by 201 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 215004.73
The remainder is 27 after subtracting 603 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 11:
When dividing 270 by 201, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 215004.731
The remainder is 69 after subtracting 201 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
201 can be fit into 690 3 times, resulting in a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 215004.7313
Subtracting 603 from 690 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
If we divide 870 by 201, we get 4 and a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 215004.73134
If we subtract 804 from 870, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
201 goes into 660 3 times with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 215004.731343
The remainder is 57 after subtracting 603 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 15:
If we divide 570 by 201, we get 2 and a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 215004.7313432
If we take 402 away from 570, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 16:
The number 201 fits into 1680 8 times, leaving a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 215004.73134328
Subtract 1608 from 1680 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 215004.73134328 with a remaining 7.2e-08.
