29312389 ÷ 7 
Our goal is to divide 29312389 by 7.

Moving on to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Advancing to step 2:
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: 4.0
Subtract 28 from 29 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 7

Advancing to step 3:
When dividing 13 by 7, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 7 from 13 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 7

On to step 4:
7 can be fit into 61 8 times, resulting in a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 418.0
Subtracting 56 from 61 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 7

On to step 5:
7 can be fit into 52 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 4187.0
If we take 49 away from 52, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 7

On to step 6:
7 goes into 33 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 41874.0
If we subtract 28 from 33, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 7

Moving on to step 7:
If we divide 58 by 7, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 418748.0
Subtract 56 from 58 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

Step 8:
If we divide 29 by 7, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4187484.0
The remainder is 1 after subtracting 28 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 4187484.1
Subtracting 7 from 10 leaves us 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.

Advancing to step 10:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4187484.14
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.

Going ahead to step 11:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 4187484.142
Deduct 14 from 20 and we're left 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.

On to step 12:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 4187484.1428
Subtract 56 from 60 to 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 13:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4187484.14285
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.

Step 14:
If we divide 50 by 7, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 4187484.142857
If we subtract 49 from 50, we get 1.
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 15:
If we divide 10 by 7, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 4187484.1428571
Deduct 7 from 10 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.

Advancing to step 16:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4187484.14285714
If we take 28 away from 30, we end up 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.

In conclusion, the division gives 4187484.14285714 with a balance of 2e-09.
