Let's divide 51298937 by 7
We want to divide 51298937 by 7.

Advancing to step 1:
If we divide 5 by 7, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 7

Let's proceed to step 2:
7 can be fit into 51 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 49 from 51 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 7

Let's proceed to step 3:
The number 7 fits into 22 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 1 after subtracting 21 from 22.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

Moving on to step 4:
The number 7 fits into 19 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 732.0
If we take 14 away from 19, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 7

Going ahead to step 5:
7 can be fit into 58 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7328.0
If we take 56 away from 58, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 7

Advancing to step 6:
When dividing 29 by 7, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 73284.0
Subtract 28 from 29 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 7

On to step 7:
13 divided by 7 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 732841.0
If we take 7 away from 13, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 7

On to step 8:
7 can be fit into 67 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 7328419.0
Subtracting 63 from 67 leaves us 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.

Going ahead to step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 7328419.5
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.

On to step 10:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 7328419.57
The remainder is 1 after subtracting 49 from 50.
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:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7328419.571
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.

Going ahead to step 12:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 7328419.5714
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.

Going ahead to step 13:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 7328419.57142
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 14:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 7328419.571428
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.

Advancing to step 15:
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: 7328419.5714285
Subtracting 35 from 40 leaves us 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.

On to step 16:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7328419.57142857
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 7328419.57142857, with a leftover of 1e-09.
