405164 ÷ 7 
We want to figure out the number of times 405164 can be divided by 7.

Step 1:
When dividing 4 by 7, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 7

Step 2:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 35 from 40 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 7

Let's proceed to step 3:
The number 7 fits into 55 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 57.0
The remainder is 6 after subtracting 49 from 55.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 7

Going ahead to step 4:
7 can be fit into 61 8 times, resulting in a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 578.0
The remainder is 5 after subtracting 56 from 61.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 7

Advancing to step 5:
7 can be fit into 56 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 5788.0
Subtract 56 from 56 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 7

Going ahead to step 6:
The number 7 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 57880.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 57880.5
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.

Moving on to step 8:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 57880.57
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.

Advancing to step 9:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 57880.571
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.

Step 10:
7 goes into 30 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 57880.5714
Subtract 28 from 30 to 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.

Step 11:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 57880.57142
Subtract 14 from 20 to get 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 12:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 57880.571428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
7 goes into 40 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 57880.5714285
If we subtract 35 from 40, we get 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 14:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 57880.57142857
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.

The final result is 57880.57142857 with a remainder of 1e-09.
