72918400 ÷ 7 
We're looking to find how many times 7 goes into 72918400.

On to step 1:
7 divided by 7 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 7 away from 7, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 7

Moving on to step 2:
When dividing 2 by 7, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 2, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Moving on to step 3:
If we divide 29 by 7, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtract 28 from 29 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 7

Let's proceed to step 4:
7 can be fit into 11 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1041.0
Subtracting 7 from 11 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 7

Going ahead to step 5:
The number 7 fits into 48 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 10416.0
If we take 42 away from 48, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 7

Moving on to step 6:
7 can be fit into 64 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 104169.0
Subtracting 63 from 64 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 7

On to step 7:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1041691.0
Subtracting 7 from 10 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 7

Let's proceed to step 8:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 10416914.0
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
20 divided by 7 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 10416914.2
If we subtract 14 from 20, we 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.

Let's proceed to step 10:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 10416914.28
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.

Let's proceed to step 11:
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: 10416914.285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 10416914.2857
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.

On to step 13:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 10416914.28571
The remainder is 3 after subtracting 7 from 10.
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 14:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 10416914.285714
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.

Let's proceed to step 15:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 10416914.2857142
The remainder is 6 after subtracting 14 from 20.
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 16:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10416914.28571428
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.

After the division, we end up with 10416914.28571428 and a remainder of 4e-09.
