748645 ÷ 7 
Our goal is to divide 748645 by 7.

Going ahead to step 1:
7 can be fit into 7 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 7 from 7 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 7

Going ahead to step 2:
7 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 7

Going ahead to step 3:
48 divided by 7 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtracting 42 from 48 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 7

Going ahead to step 4:
7 goes into 66 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 1069.0
If we subtract 63 from 66, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 7

On to step 5:
7 goes into 34 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 10694.0
If we subtract 28 from 34, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 7

Going ahead to step 6:
When dividing 65 by 7, we get 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 106949.0
If we subtract 63 from 65, 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.

On to step 7:
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: 106949.2
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.

On to step 8:
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: 106949.28
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.

Moving on to step 9:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 106949.285
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.

On to step 10:
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: 106949.2857
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.

Moving on to step 11:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 106949.28571
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.

On to step 12:
If we divide 30 by 7, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 106949.285714
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.

Step 13:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 106949.2857142
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.

On to step 14:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 106949.28571428
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.

After the division, we end up with 106949.28571428 and a remainder of 4e-09.
