We divide 42021515 by 590
The aim is to understand the frequency of 590 in 42021515.

On to step 1:
If we divide 4 by 590, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 590

Step 2:
590 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 590

On to step 3:
590 goes into 420 0 times with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 420, we end up with 420.
Include the next digit (2) from the dividend after 420, then repeat: 4202 / 590

Going ahead to step 4:
590 can be fit into 4202 7 times, resulting in a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4130 from 4202 leaves us with 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 590

Let's proceed to step 5:
590 can be fit into 721 1 times, resulting in a remainder of 131.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 590 away from 721, we end up with 131.
Take the next digit (5) from the dividend and append it to 131, then repeat: 1315 / 590

Step 6:
The number 590 fits into 1315 2 times, leaving a remainder of 135.
Put 2 as the next digit of the answer. 
Result so far: 712.0
Deduct 1180 from 1315 and we're left with 135.
Take the next digit (1) from the dividend and append it to 135, then repeat: 1351 / 590

Advancing to step 7:
If we divide 1351 by 590, we get 2 and a remainder of 171.
Write down 2 as next digit of the result. 
Result so far: 7122.0
If we take 1180 away from 1351, we end up with 171.
Grab the next digit (5) from the dividend, add it to 171, then carry on: 1715 / 590

Step 8:
When dividing 1715 by 590, we get 2 with a remainder of 535.
Record the quotient 2 as the next digit in the result. 
Result so far: 71222.0
The remainder is 535 after subtracting 1180 from 1715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 9:
The number 590 fits into 5350 9 times, leaving a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 71222.9
If we take 5310 away from 5350, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
590 can be fit into 400 0 times, resulting in a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 71222.9
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
If we divide 4000 by 590, we get 6 and a remainder of 460.
Write down 6 as next digit of the result. 
Result so far: 71222.906
Subtract 3540 from 4000 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 12:
The number 590 fits into 4600 7 times, leaving a remainder of 470.
Record the quotient 7 as the next digit in the result. 
Result so far: 71222.9067
Deduct 4130 from 4600 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 13:
The number 590 fits into 4700 7 times, leaving a remainder of 570.
Use 7 as the next digit of our solution. 
Result so far: 71222.90677
Subtracting 4130 from 4700 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

The final outcome is 71222.90677, with a leftover of 0.00057.
