We divide 86428432 by 673
The aim is to understand the frequency of 673 in 86428432.

Step 1:
8 divided by 673 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 673

Step 2:
673 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 673

On to step 3:
If we divide 864 by 673, we get 1 and a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 673 from 864 leaves us with 191.
Append the next digit (2) from the dividend to 191 and continue with: 1912 / 673

Advancing to step 4:
If we divide 1912 by 673, we get 2 and a remainder of 566.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1346 from 1912 to get 566.
Include the next digit (8) from the dividend after 566, then repeat: 5668 / 673

Step 5:
673 can be fit into 5668 8 times, resulting in a remainder of 284.
The next digit of our result is 8. 
Result so far: 128.0
If we take 5384 away from 5668, we end up with 284.
Include the next digit (4) from the dividend after 284, then repeat: 2844 / 673

Moving on to step 6:
If we divide 2844 by 673, we get 4 and a remainder of 152.
The next digit of our result is 4. 
Result so far: 1284.0
If we subtract 2692 from 2844, we get 152.
Fetch the next digit (3) from the dividend, attach it to 152 and continue: 1523 / 673

On to step 7:
The number 673 fits into 1523 2 times, leaving a remainder of 177.
Write down 2 as next digit of the result. 
Result so far: 12842.0
The remainder is 177 after subtracting 1346 from 1523.
Include the next digit (2) from the dividend after 177, then repeat: 1772 / 673

Let's proceed to step 8:
When dividing 1772 by 673, we get 2 with a remainder of 426.
Use 2 as the next digit of our solution. 
Result so far: 128422.0
Deduct 1346 from 1772 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Step 9:
The number 673 fits into 4260 6 times, leaving a remainder of 222.
Record the quotient 6 as the next digit in the result. 
Result so far: 128422.6
The remainder is 222 after subtracting 4038 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 10:
The number 673 fits into 2220 3 times, leaving a remainder of 201.
The next digit of our result is 3. 
Result so far: 128422.63
If we take 2019 away from 2220, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 11:
The number 673 fits into 2010 2 times, leaving a remainder of 664.
Write down 2 as next digit of the result. 
Result so far: 128422.632
Subtract 1346 from 2010 to get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Moving on to step 12:
6640 divided by 673 is 9 with a remainder of 583.
Put 9 as the next digit of the answer. 
Result so far: 128422.6329
If we subtract 6057 from 6640, we get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Let's proceed to step 13:
5830 divided by 673 is 8 with a remainder of 446.
Put 8 as the next digit of the answer. 
Result so far: 128422.63298
Deduct 5384 from 5830 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 14:
673 can be fit into 4460 6 times, resulting in a remainder of 422.
The next digit of our result is 6. 
Result so far: 128422.632986
Subtracting 4038 from 4460 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 15:
The number 673 fits into 4220 6 times, leaving a remainder of 182.
Use 6 as the next digit of our solution. 
Result so far: 128422.6329866
Deduct 4038 from 4220 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final outcome is 128422.6329866, with a leftover of 1.82e-06.
