We look at the division of 63604424 by 167 
The aim is to understand the frequency of 167 in 63604424.

On to step 1:
167 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 167

Advancing to step 2:
167 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 167

Moving on to step 3:
The number 167 fits into 636 3 times, leaving a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 501 from 636, we get 135.
Append the next digit (0) from the dividend to 135 and continue with: 1350 / 167

Step 4:
When dividing 1350 by 167, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 1336 from 1350 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 167

Step 5:
144 divided by 167 is 0 with a remainder of 144.
Write down 0 as next digit of the result. 
Result so far: 380.0
If we subtract 0 from 144, we get 144.
Bring next digit (4) of the dividend behind the 144 and repeat the process: 1444 / 167

Advancing to step 6:
1444 divided by 167 is 8 with a remainder of 108.
Record the quotient 8 as the next digit in the result. 
Result so far: 3808.0
If we take 1336 away from 1444, we end up with 108.
Fetch the next digit (2) from the dividend, attach it to 108 and continue: 1082 / 167

Let's proceed to step 7:
1082 divided by 167 is 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 38086.0
Subtract 1002 from 1082 to get 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 167

Step 8:
When dividing 804 by 167, we get 4 with a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 380864.0
Deduct 668 from 804 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 9:
167 can be fit into 1360 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 380864.8
Deduct 1336 from 1360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
When dividing 240 by 167, we get 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 380864.81
Subtracting 167 from 240 leaves us 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 11:
730 divided by 167 is 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 380864.814
If we subtract 668 from 730, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 12:
If we divide 620 by 167, we get 3 and a remainder of 119.
The next digit of our result is 3. 
Result so far: 380864.8143
The remainder is 119 after subtracting 501 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 13:
167 can be fit into 1190 7 times, resulting in a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 380864.81437
Deduct 1169 from 1190 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
167 goes into 210 1 times with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 380864.814371
Deduct 167 from 210 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 15:
If we divide 430 by 167, we get 2 and a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 380864.8143712
Subtract 334 from 430 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 16:
The number 167 fits into 960 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 380864.81437125
Subtract 835 from 960 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final outcome is 380864.81437125, with a leftover of 1.25e-07.
