We're dividing 89878423 by 590 
The aim is to understand the frequency of 590 in 89878423.

Let's proceed to step 1:
8 divided by 590 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 590

Step 2:
If we divide 89 by 590, we get 0 and a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (8) from the dividend after 89, then repeat: 898 / 590

Going ahead to step 3:
The number 590 fits into 898 1 times, leaving a remainder of 308.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 590 away from 898, we end up with 308.
Include the next digit (7) from the dividend after 308, then repeat: 3087 / 590

Advancing to step 4:
The number 590 fits into 3087 5 times, leaving a remainder of 137.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 137 after subtracting 2950 from 3087.
Include the next digit (8) from the dividend after 137, then repeat: 1378 / 590

Going ahead to step 5:
590 goes into 1378 2 times with a remainder of 198.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtracting 1180 from 1378 leaves us with 198.
Include the next digit (4) from the dividend after 198, then repeat: 1984 / 590

Advancing to step 6:
590 goes into 1984 3 times with a remainder of 214.
Write down 3 as next digit of the result. 
Result so far: 1523.0
The remainder is 214 after subtracting 1770 from 1984.
Fetch the next digit (2) from the dividend, attach it to 214 and continue: 2142 / 590

Step 7:
The number 590 fits into 2142 3 times, leaving a remainder of 372.
Put 3 as the next digit of the answer. 
Result so far: 15233.0
Subtract 1770 from 2142 to get 372.
Include the next digit (3) from the dividend after 372, then repeat: 3723 / 590

Let's proceed to step 8:
The number 590 fits into 3723 6 times, leaving a remainder of 183.
Use 6 as the next digit of our solution. 
Result so far: 152336.0
If we take 3540 away from 3723, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 9:
590 can be fit into 1830 3 times, resulting in a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 152336.3
If we subtract 1770 from 1830, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
The number 590 fits into 600 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 152336.31
Subtracting 590 from 600 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
If we divide 100 by 590, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 152336.31
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
590 can be fit into 1000 1 times, resulting in a remainder of 410.
Put 1 as the next digit of the answer. 
Result so far: 152336.3101
If we subtract 590 from 1000, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 13:
When dividing 4100 by 590, we get 6 with a remainder of 560.
Use 6 as the next digit of our solution. 
Result so far: 152336.31016
If we take 3540 away from 4100, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 14:
590 goes into 5600 9 times with a remainder of 290.
Record the quotient 9 as the next digit in the result. 
Result so far: 152336.310169
If we take 5310 away from 5600, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 15:
When dividing 2900 by 590, we get 4 with a remainder of 540.
Write down 4 as next digit of the result. 
Result so far: 152336.3101694
Subtracting 2360 from 2900 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 16:
590 can be fit into 5400 9 times, resulting in a remainder of 90.
Write down 9 as next digit of the result. 
Result so far: 152336.31016949
If we subtract 5310 from 5400, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 152336.31016949 and a remainder of 9e-08.
