We divide 83604 by 74
The aim is to understand the frequency of 74 in 83604.

Step 1:
8 divided by 74 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 74

Moving on to step 2:
83 divided by 74 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 74 from 83, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 74

Moving on to step 3:
74 goes into 96 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 74 from 96, we get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 74

Let's proceed to step 4:
When dividing 220 by 74, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we take 148 away from 220, we end up with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 74

On to step 5:
74 goes into 724 9 times with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 1129.0
If we take 666 away from 724, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 6:
The number 74 fits into 580 7 times, leaving a remainder of 62.
The next digit of our result is 7. 
Result so far: 1129.7
The remainder is 62 after subtracting 518 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
If we divide 620 by 74, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 1129.78
Deduct 592 from 620 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
When dividing 280 by 74, we get 3 with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 1129.783
Deduct 222 from 280 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
The number 74 fits into 580 7 times, leaving a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 1129.7837
Subtracting 518 from 580 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
When dividing 620 by 74, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 1129.78378
If we take 592 away from 620, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
The number 74 fits into 280 3 times, leaving a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 1129.783783
If we subtract 222 from 280, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
74 can be fit into 580 7 times, resulting in a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 1129.7837837
Subtract 518 from 580 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
When dividing 620 by 74, we get 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 1129.78378378
If we subtract 592 from 620, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 1129.78378378 and a remainder of 2.8e-08.
