We look at the division of 30665748 by 7 
Our goal is to divide 30665748 by 7.

Step 1:
The number 7 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 7

Advancing to step 2:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 28 from 30, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 7

Let's proceed to step 3:
7 goes into 26 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we subtract 21 from 26, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 7

Going ahead to step 4:
The number 7 fits into 56 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 438.0
The remainder is 0 after subtracting 56 from 56.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 7

Step 5:
5 divided by 7 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 4380.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 7

Let's proceed to step 6:
7 can be fit into 57 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 43808.0
Deduct 56 from 57 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 7

Step 7:
7 can be fit into 14 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 438082.0
Deduct 14 from 14 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 7

On to step 8:
When dividing 8 by 7, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 4380821.0
Subtract 7 from 8 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 4380821.1
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4380821.14
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 4380821.142
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
60 divided by 7 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 4380821.1428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4380821.14285
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 4380821.142857
Deduct 49 from 50 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 15:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 4380821.1428571
Subtract 7 from 10 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 16:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4380821.14285714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 4380821.14285714 and a remainder of 2e-09.
