We divide 51940129 by 7
We want to figure out the number of times 51940129 can be divided by 7.

Step 1:
5 divided by 7 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 7

Moving on to step 2:
7 goes into 51 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 49 from 51 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

Going ahead to step 3:
If we divide 29 by 7, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Deduct 28 from 29 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 7

Moving on to step 4:
If we divide 14 by 7, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 742.0
If we take 14 away from 14, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 7

Step 5:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7420.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 7

Moving on to step 6:
7 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 74200.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 7

Let's proceed to step 7:
If we divide 12 by 7, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 742001.0
Subtract 7 from 12 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 7

On to step 8:
7 can be fit into 59 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 7420018.0
Deduct 56 from 59 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.

Let's proceed to 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: 7420018.4
Deduct 28 from 30 and we're left 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.

Going ahead to step 10:
7 goes into 20 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 7420018.42
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 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: 7420018.428
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.

Advancing to step 12:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7420018.4285
Deduct 35 from 40 and we're left 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 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: 7420018.42857
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 14:
7 goes into 10 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 7420018.428571
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.

Advancing to step 15:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 7420018.4285714
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.

Let's proceed to step 16:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 7420018.42857142
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.

Our division results in 7420018.42857142 with a remaining 6e-09.
