126594 ÷ 30 
We're looking to find how many times 30 goes into 126594.

On to step 1:
1 divided by 30 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 30

Step 2:
30 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 30

Moving on to step 3:
30 goes into 126 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 120 from 126, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 30

Advancing to step 4:
If we divide 65 by 30, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 60 from 65, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 30

Moving on to step 5:
The number 30 fits into 59 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 421.0
Deduct 30 from 59 and we're left with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 30

Advancing to step 6:
30 goes into 294 9 times with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 4219.0
Deduct 270 from 294 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
The number 30 fits into 240 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 4219.8
Deduct 240 from 240 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
30 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4219.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4219.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4219.8 with a remaining 0.0.
