75436039 ÷ 290 
The aim is to understand the frequency of 290 in 75436039.

On to step 1:
The number 290 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 290

Let's proceed to step 2:
290 goes into 75 0 times with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 290

Advancing to step 3:
290 goes into 754 2 times with a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 580 from 754, we get 174.
Append the next digit (3) from the dividend to 174 and continue with: 1743 / 290

On to step 4:
The number 290 fits into 1743 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 1740 from 1743 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 290

Step 5:
36 divided by 290 is 0 with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 260.0
Subtracting 0 from 36 leaves us with 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 290

Let's proceed to step 6:
360 divided by 290 is 1 with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 2601.0
Subtracting 290 from 360 leaves us with 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 290

On to step 7:
The number 290 fits into 703 2 times, leaving a remainder of 123.
The number 2 becomes the next digit in our result. 
Result so far: 26012.0
If we take 580 away from 703, we end up with 123.
Fetch the next digit (9) from the dividend, attach it to 123 and continue: 1239 / 290

Moving on to step 8:
290 can be fit into 1239 4 times, resulting in a remainder of 79.
Use 4 as the next digit of our solution. 
Result so far: 260124.0
If we subtract 1160 from 1239, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
790 divided by 290 is 2 with a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 260124.2
If we subtract 580 from 790, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
290 can be fit into 2100 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 260124.27
Subtracting 2030 from 2100 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
When dividing 700 by 290, we get 2 with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 260124.272
If we take 580 away from 700, we end up 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.

Step 12:
If we divide 1200 by 290, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 260124.2724
If we subtract 1160 from 1200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
290 can be fit into 400 1 times, resulting in a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 260124.27241
The remainder is 110 after subtracting 290 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 14:
When dividing 1100 by 290, we get 3 with a remainder of 230.
Write down 3 as next digit of the result. 
Result so far: 260124.272413
Deduct 870 from 1100 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 15:
The number 290 fits into 2300 7 times, leaving a remainder of 270.
The next digit of our result is 7. 
Result so far: 260124.2724137
If we take 2030 away from 2300, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 16:
When dividing 2700 by 290, we get 9 with a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 260124.27241379
Deduct 2610 from 2700 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 260124.27241379, with a leftover of 9e-08.
