61 divided by 7 is 8 with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 56 from 61 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 7

Moving on to step 3:
When dividing 57 by 7, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 56 from 57 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 7

On to step 4:
If we divide 18 by 7, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 882.0
Subtracting 14 from 18 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 7

Going ahead to step 5:
45 divided by 7 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 8826.0
Subtract 42 from 45 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 7

Step 6:
If we divide 31 by 7, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 88264.0
The remainder is 3 after subtracting 28 from 31.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 7

Advancing to step 7:
7 can be fit into 34 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 882644.0
If we subtract 28 from 34, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 7

Advancing to step 8:
If we divide 65 by 7, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 8826449.0
Subtracting 63 from 65 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.

Advancing 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: 8826449.2
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.

Let's proceed to step 10:
If we divide 60 by 7, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 8826449.28
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.

On to step 11:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 8826449.285
Subtract 35 from 40 to 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.

Going ahead to step 12:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 8826449.2857
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.

Step 13:
10 divided by 7 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 8826449.28571
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.

Moving on to step 14:
When dividing 30 by 7, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 8826449.285714
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.

Let's proceed to step 15:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 8826449.2857142
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.

On to step 16:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 8826449.28571428
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.

Our division results in 8826449.28571428 with a remaining 4e-09.
