3929289 divided by 120 
We want to figure out the number of times 3929289 can be divided by 120.

Step 1:
3 divided by 120 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 120

Step 2:
120 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 120

On to step 3:
If we divide 392 by 120, we get 3 and a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 360 from 392 and we're left with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 120

Moving on to step 4:
329 divided by 120 is 2 with a remainder of 89.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 240 from 329, we get 89.
Take the next digit (2) from the dividend and append it to 89, then repeat: 892 / 120

On to step 5:
120 goes into 892 7 times with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 327.0
If we take 840 away from 892, we end up with 52.
Grab the next digit (8) from the dividend, add it to 52, then carry on: 528 / 120

Let's proceed to step 6:
The number 120 fits into 528 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 3274.0
Deduct 480 from 528 and we're left with 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 120

Let's proceed to step 7:
489 divided by 120 is 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 32744.0
Subtract 480 from 489 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
When dividing 90 by 120, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 32744.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 9:
900 divided by 120 is 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 32744.07
If we take 840 away from 900, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
600 divided by 120 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 32744.075
Subtracting 600 from 600 leaves us 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 11:
The number 120 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 32744.075
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.

Going ahead to step 12:
120 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32744.075
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.

The final outcome is 32744.075, with a leftover of 0.0.
