We look at the division of 45745865 by 7 
We want to figure out the number of times 45745865 can be divided by 7.

Step 1:
7 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 7

Moving on to step 2:
If we divide 45 by 7, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 42 from 45 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 7

Let's proceed to step 3:
37 divided by 7 is 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 35 from 37 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 7

Step 4:
If we divide 24 by 7, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 653.0
If we take 21 away from 24, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 7

Let's proceed to step 5:
If we divide 35 by 7, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6535.0
If we take 35 away from 35, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 7

Let's proceed to step 6:
8 divided by 7 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 65351.0
Subtract 7 from 8 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 7

Advancing to step 7:
If we divide 16 by 7, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 653512.0
If we take 14 away from 16, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 7

Advancing to step 8:
7 goes into 25 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 6535123.0
The remainder is 4 after subtracting 21 from 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6535123.5
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.

Let's proceed to step 10:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 6535123.57
Subtracting 49 from 50 leaves us 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.

Moving on to step 11:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 6535123.571
If we subtract 7 from 10, we 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.

On to step 12:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 6535123.5714
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.

Advancing to step 13:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 6535123.57142
If we take 14 away from 20, we end up 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 14:
7 goes into 60 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 6535123.571428
If we take 56 away from 60, we end up 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.

Advancing to step 15:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6535123.5714285
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.

Moving on to step 16:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 6535123.57142857
If we take 49 away from 50, we end up 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.

The final outcome is 6535123.57142857, with a leftover of 1e-09.
