We're dividing 521936 by 74 
The aim is to understand the frequency of 74 in 521936.

Moving on to step 1:
When dividing 5 by 74, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 74

Moving on to step 2:
When dividing 52 by 74, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 74

Advancing to step 3:
If we divide 521 by 74, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 518 from 521 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 74

Let's proceed to step 4:
39 divided by 74 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 74

Moving on to step 5:
74 can be fit into 393 5 times, resulting in a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 705.0
Subtracting 370 from 393 leaves us with 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 74

Going ahead to step 6:
If we divide 236 by 74, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 7053.0
Subtract 222 from 236 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
74 goes into 140 1 times with a remainder of 66.
The next digit of our result is 1. 
Result so far: 7053.1
If we subtract 74 from 140, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
If we divide 660 by 74, we get 8 and a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 7053.18
Deduct 592 from 660 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
If we divide 680 by 74, we get 9 and a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 7053.189
If we take 666 away from 680, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
74 can be fit into 140 1 times, resulting in a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 7053.1891
Subtracting 74 from 140 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
When dividing 660 by 74, we get 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 7053.18918
Deduct 592 from 660 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
74 goes into 680 9 times with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 7053.189189
Subtract 666 from 680 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
74 can be fit into 140 1 times, resulting in a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 7053.1891891
Subtract 74 from 140 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
The number 74 fits into 660 8 times, leaving a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 7053.18918918
Subtracting 592 from 660 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 7053.18918918, with a leftover of 6.8e-08.
