Let's divide 526421 by 73
The aim is to understand the frequency of 73 in 526421.

Let's proceed to step 1:
73 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 73

Moving on to step 2:
52 divided by 73 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 73

Moving on to step 3:
73 can be fit into 526 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 511 away from 526, we end up with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 73

Advancing to step 4:
73 can be fit into 154 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtracting 146 from 154 leaves us with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 73

Advancing to step 5:
73 can be fit into 82 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 721.0
The remainder is 9 after subtracting 73 from 82.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 73

Let's proceed to step 6:
73 goes into 91 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 7211.0
Subtract 73 from 91 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
If we divide 180 by 73, we get 2 and a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 7211.2
The remainder is 34 after subtracting 146 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
340 divided by 73 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 7211.24
Subtracting 292 from 340 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
When dividing 480 by 73, we get 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 7211.246
If we subtract 438 from 480, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
73 can be fit into 420 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 7211.2465
Subtract 365 from 420 to get 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 11:
When dividing 550 by 73, we get 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 7211.24657
Deduct 511 from 550 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 12:
When dividing 390 by 73, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7211.246575
Subtracting 365 from 390 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
If we divide 250 by 73, we get 3 and a remainder of 31.
The next digit of our result is 3. 
Result so far: 7211.2465753
Subtract 219 from 250 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
73 goes into 310 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 7211.24657534
Subtract 292 from 310 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 7211.24657534, with a leftover of 1.8e-08.
