We're dividing 638832 by 7 
We want to figure out the number of times 638832 can be divided by 7.

Let's proceed to step 1:
When dividing 6 by 7, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 7

On to step 2:
7 goes into 63 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 63 from 63 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 7

On to step 3:
7 goes into 8 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 91.0
If we take 7 away from 8, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 7

Advancing to step 4:
7 goes into 18 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 912.0
Subtracting 14 from 18 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 7

Step 5:
When dividing 43 by 7, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 9126.0
Subtract 42 from 43 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 7

Let's proceed to step 6:
7 goes into 12 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 91261.0
The remainder is 5 after subtracting 7 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 7, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 91261.7
If we subtract 49 from 50, we 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.

Moving on to step 8:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 91261.71
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 9:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 91261.714
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.

Moving on to step 10:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 91261.7142
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.

Moving on to step 11:
If we divide 60 by 7, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 91261.71428
Deduct 56 from 60 and we're left with 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 12:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 91261.714285
Subtracting 35 from 40 leaves us 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.

Advancing to step 13:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 91261.7142857
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.

On to step 14:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 91261.71428571
Deduct 7 from 10 and we're left 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.

The final outcome is 91261.71428571, with a leftover of 3e-09.
