525121 divided by 74 
Our goal is to divide 525121 by 74.

Step 1:
If we divide 5 by 74, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 74

Let's proceed to step 2:
74 can be fit into 52 0 times, resulting in a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 74

On to step 3:
74 can be fit into 525 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 518 from 525 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 74

Moving on to step 4:
74 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 74

On to step 5:
712 divided by 74 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 709.0
If we subtract 666 from 712, we get 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 74

On to step 6:
If we divide 461 by 74, we get 6 and a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 7096.0
Deduct 444 from 461 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 74 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 7096.2
Deduct 148 from 170 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
74 goes into 220 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 7096.22
If we subtract 148 from 220, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 7096.22 with a remaining 0.072.
