978289 divided by 7 
Our goal is to divide 978289 by 7.

Advancing to step 1:
If we divide 9 by 7, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 7 from 9, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 7

Moving on to step 2:
When dividing 27 by 7, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 21 from 27 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 7

Step 3:
7 can be fit into 68 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 139.0
Subtract 63 from 68 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 7

Advancing to step 4:
When dividing 52 by 7, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1397.0
The remainder is 3 after subtracting 49 from 52.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 7

Going ahead to step 5:
If we divide 38 by 7, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 13975.0
If we take 35 away from 38, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 7

Advancing to step 6:
The number 7 fits into 39 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 139755.0
If we take 35 away from 39, we end up 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.

Let's proceed to step 7:
When dividing 40 by 7, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 139755.5
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 139755.57
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.

Step 9:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 139755.571
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.

Let's proceed to step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 139755.5714
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.

Let's proceed to step 11:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 139755.57142
If we take 14 away from 20, we end up 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 12:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 139755.571428
If we take 56 away from 60, we end up 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.

Step 13:
If we divide 40 by 7, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 139755.5714285
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.

Advancing to step 14:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 139755.57142857
Deduct 49 from 50 and we're left 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.

In conclusion, the division gives 139755.57142857 with a balance of 1e-09.
