52505588 ÷ 7 
Our goal is to divide 52505588 by 7.

Going ahead to step 1:
5 divided by 7 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 7

Let's proceed to step 2:
If we divide 52 by 7, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 3 after subtracting 49 from 52.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 7

Advancing to step 3:
The number 7 fits into 35 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 35 from 35, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 7

Going ahead to step 4:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 750.0
If we subtract 0 from 0, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 7

Moving on to step 5:
7 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 7500.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 7

Moving on to step 6:
7 can be fit into 55 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 75007.0
Subtract 49 from 55 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 7

Step 7:
When dividing 68 by 7, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 750079.0
The remainder is 5 after subtracting 63 from 68.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 7

On to step 8:
7 goes into 58 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 7500798.0
Subtracting 56 from 58 leaves us 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.

Let's proceed 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: 7500798.2
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 7500798.28
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.

On to step 11:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7500798.285
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.

Moving on to step 12:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7500798.2857
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.

Advancing to step 13:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 7500798.28571
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.

Advancing to step 14:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 7500798.285714
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 15:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 7500798.2857142
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.

Step 16:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 7500798.28571428
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.

The final outcome is 7500798.28571428, with a leftover of 4e-09.
