We're dividing 70063201 by 171 
The aim is to understand the frequency of 171 in 70063201.

Let's proceed to step 1:
The number 171 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 171

Moving on to step 2:
70 divided by 171 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 171

On to step 3:
If we divide 700 by 171, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 684 away from 700, we end up with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 171

On to step 4:
171 can be fit into 166 0 times, resulting in a remainder of 166.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 166 and we're left with 166.
Grab the next digit (3) from the dividend, add it to 166, then carry on: 1663 / 171

Advancing to step 5:
171 goes into 1663 9 times with a remainder of 124.
Use 9 as the next digit of our solution. 
Result so far: 409.0
If we subtract 1539 from 1663, we get 124.
Bring next digit (2) of the dividend behind the 124 and repeat the process: 1242 / 171

Going ahead to step 6:
The number 171 fits into 1242 7 times, leaving a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 4097.0
If we take 1197 away from 1242, we end up with 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 171

Let's proceed to step 7:
171 goes into 450 2 times with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 40972.0
Deduct 342 from 450 and we're left with 108.
Grab the next digit (1) from the dividend, add it to 108, then carry on: 1081 / 171

Step 8:
The number 171 fits into 1081 6 times, leaving a remainder of 55.
The next digit of our result is 6. 
Result so far: 409726.0
Deduct 1026 from 1081 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
The number 171 fits into 550 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 409726.3
Subtracting 513 from 550 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
171 goes into 370 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 409726.32
Subtracting 342 from 370 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
When dividing 280 by 171, we get 1 with a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 409726.321
The remainder is 109 after subtracting 171 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 12:
The number 171 fits into 1090 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 409726.3216
Subtracting 1026 from 1090 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
171 can be fit into 640 3 times, resulting in a remainder of 127.
Put 3 as the next digit of the answer. 
Result so far: 409726.32163
Deduct 513 from 640 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 14:
The number 171 fits into 1270 7 times, leaving a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 409726.321637
Deduct 1197 from 1270 and we're left 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.

Advancing to step 15:
730 divided by 171 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 409726.3216374
Subtract 684 from 730 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 16:
460 divided by 171 is 2 with a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 409726.32163742
Deduct 342 from 460 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The quotient of the division is 409726.32163742, and the remainder is 1.18e-07.
