We're dividing 738990 by 7 
We want to figure out the number of times 738990 can be divided by 7.

Advancing to step 1:
7 goes into 7 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 7 from 7.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 7

On to step 2:
7 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 7

Going ahead to step 3:
7 goes into 38 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 105.0
Deduct 35 from 38 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 7

Let's proceed to step 4:
39 divided by 7 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 1055.0
If we take 35 away from 39, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 7

On to step 5:
49 divided by 7 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 10557.0
Deduct 49 from 49 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 7

Step 6:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 105570.0
Subtracting 0 from 0 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 7:
0 divided by 7 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 105570.0
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.

Going ahead to step 8:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 105570.0
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.

After the division, we end up with 105570.0 and a remainder of 0.0.
