51064328 ÷ 7 
We're looking to find how many times 7 goes into 51064328.

On to step 1:
7 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 7

Going ahead to step 2:
If we divide 51 by 7, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 49 from 51 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 7

Advancing to step 3:
When dividing 20 by 7, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtract 14 from 20 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 7

Let's proceed to step 4:
When dividing 66 by 7, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 729.0
If we subtract 63 from 66, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 7

Moving on to step 5:
7 goes into 34 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 7294.0
If we subtract 28 from 34, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 7

Going ahead to step 6:
7 can be fit into 63 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 72949.0
Subtracting 63 from 63 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 7

Let's proceed to step 7:
7 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 729490.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 7

Moving on to step 8:
7 can be fit into 28 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 7294904.0
Deduct 28 from 28 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 7, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7294904.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7294904.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 7294904.0, and the remainder is 0.0.
