Let's divide 63953516 by 161
The aim is to understand the frequency of 161 in 63953516.

Step 1:
6 divided by 161 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 161

Let's proceed to step 2:
If we divide 63 by 161, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 161

Step 3:
If we divide 639 by 161, we get 3 and a remainder of 156.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 483 from 639 to get 156.
Bring next digit (5) of the dividend behind the 156 and repeat the process: 1565 / 161

Let's proceed to step 4:
If we divide 1565 by 161, we get 9 and a remainder of 116.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 1449 from 1565 to get 116.
Append the next digit (3) from the dividend to 116 and continue with: 1163 / 161

On to step 5:
The number 161 fits into 1163 7 times, leaving a remainder of 36.
The next digit of our result is 7. 
Result so far: 397.0
Subtracting 1127 from 1163 leaves us with 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 161

On to step 6:
161 goes into 365 2 times with a remainder of 43.
The number 2 becomes the next digit in our result. 
Result so far: 3972.0
If we take 322 away from 365, we end up with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 161

Going ahead to step 7:
The number 161 fits into 431 2 times, leaving a remainder of 109.
Record the quotient 2 as the next digit in the result. 
Result so far: 39722.0
If we take 322 away from 431, we end up with 109.
Append the next digit (6) from the dividend to 109 and continue with: 1096 / 161

Moving on to step 8:
If we divide 1096 by 161, we get 6 and a remainder of 130.
Write down 6 as next digit of the result. 
Result so far: 397226.0
Deduct 966 from 1096 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 9:
If we divide 1300 by 161, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 397226.8
Subtract 1288 from 1300 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
When dividing 120 by 161, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 397226.8
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
The number 161 fits into 1200 7 times, leaving a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 397226.807
If we subtract 1127 from 1200, we get 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 12:
161 goes into 730 4 times with a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 397226.8074
The remainder is 86 after subtracting 644 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 13:
When dividing 860 by 161, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 397226.80745
Subtracting 805 from 860 leaves us 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 14:
550 divided by 161 is 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 397226.807453
Deduct 483 from 550 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 15:
When dividing 670 by 161, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 397226.8074534
If we subtract 644 from 670, 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.

On to step 16:
The number 161 fits into 260 1 times, leaving a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 397226.80745341
Subtract 161 from 260 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

The quotient of the division is 397226.80745341, and the remainder is 9.9e-08.
