We divide 86998389 by 164
The aim is to understand the frequency of 164 in 86998389.

On to step 1:
164 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 164

Advancing to step 2:
If we divide 86 by 164, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 164

Advancing to step 3:
164 can be fit into 869 5 times, resulting in a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 820 from 869 to get 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 164

Moving on to step 4:
The number 164 fits into 499 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we take 492 away from 499, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 164

Let's proceed to step 5:
164 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 530.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 164

Let's proceed to step 6:
164 can be fit into 783 4 times, resulting in a remainder of 127.
Put 4 as the next digit of the answer. 
Result so far: 5304.0
The remainder is 127 after subtracting 656 from 783.
Fetch the next digit (8) from the dividend, attach it to 127 and continue: 1278 / 164

Advancing to step 7:
164 goes into 1278 7 times with a remainder of 130.
The next digit of our result is 7. 
Result so far: 53047.0
If we subtract 1148 from 1278, we get 130.
Fetch the next digit (9) from the dividend, attach it to 130 and continue: 1309 / 164

Let's proceed to step 8:
When dividing 1309 by 164, we get 7 with a remainder of 161.
Write down 7 as next digit of the result. 
Result so far: 530477.0
Deduct 1148 from 1309 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 9:
The number 164 fits into 1610 9 times, leaving a remainder of 134.
The next digit of our result is 9. 
Result so far: 530477.9
Deduct 1476 from 1610 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 10:
If we divide 1340 by 164, we get 8 and a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 530477.98
Deduct 1312 from 1340 and we're left 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.

Step 11:
When dividing 280 by 164, we get 1 with a remainder of 116.
Write down 1 as next digit of the result. 
Result so far: 530477.981
Subtract 164 from 280 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 12:
If we divide 1160 by 164, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 530477.9817
Deduct 1148 from 1160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
164 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 530477.9817
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
If we divide 1200 by 164, we get 7 and a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 530477.981707
If we subtract 1148 from 1200, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 15:
520 divided by 164 is 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 530477.9817073
Subtract 492 from 520 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
164 can be fit into 280 1 times, resulting in a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 530477.98170731
The remainder is 116 after subtracting 164 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final outcome is 530477.98170731, with a leftover of 1.16e-07.
