If we divide 6 by 907, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 907

Moving on to step 2:
68 divided by 907 is 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 907

Advancing to step 3:
When dividing 684 by 907, we get 0 with a remainder of 684.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 684 and we're left with 684.
Grab the next digit (4) from the dividend, add it to 684, then carry on: 6844 / 907

On to step 4:
The number 907 fits into 6844 7 times, leaving a remainder of 495.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 6349 from 6844 and we're left with 495.
Grab the next digit (7) from the dividend, add it to 495, then carry on: 4957 / 907

Step 5:
907 can be fit into 4957 5 times, resulting in a remainder of 422.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtract 4535 from 4957 to get 422.
Include the next digit (3) from the dividend after 422, then repeat: 4223 / 907

Let's proceed to step 6:
If we divide 4223 by 907, we get 4 and a remainder of 595.
Record the quotient 4 as the next digit in the result. 
Result so far: 754.0
If we subtract 3628 from 4223, we get 595.
Take the next digit (0) from the dividend and append it to 595, then repeat: 5950 / 907

Step 7:
907 can be fit into 5950 6 times, resulting in a remainder of 508.
Write down 6 as next digit of the result. 
Result so far: 7546.0
Subtract 5442 from 5950 to get 508.
Grab the next digit (8) from the dividend, add it to 508, then carry on: 5088 / 907

Let's proceed to step 8:
The number 907 fits into 5088 5 times, leaving a remainder of 553.
Use 5 as the next digit of our solution. 
Result so far: 75465.0
Subtracting 4535 from 5088 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Advancing to step 9:
907 can be fit into 5530 6 times, resulting in a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 75465.6
The remainder is 88 after subtracting 5442 from 5530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 10:
The number 907 fits into 880 0 times, leaving a remainder of 880.
Record the quotient 0 as the next digit in the result. 
Result so far: 75465.6
If we subtract 0 from 880, we get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Going ahead to step 11:
907 can be fit into 8800 9 times, resulting in a remainder of 637.
Put 9 as the next digit of the answer. 
Result so far: 75465.609
The remainder is 637 after subtracting 8163 from 8800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

On to step 12:
907 goes into 6370 7 times with a remainder of 21.
The next digit of our result is 7. 
Result so far: 75465.6097
Subtracting 6349 from 6370 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
The number 907 fits into 210 0 times, leaving a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 75465.6097
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 14:
907 can be fit into 2100 2 times, resulting in a remainder of 286.
Put 2 as the next digit of the answer. 
Result so far: 75465.609702
Subtracting 1814 from 2100 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 15:
2860 divided by 907 is 3 with a remainder of 139.
Record the quotient 3 as the next digit in the result. 
Result so far: 75465.6097023
Deduct 2721 from 2860 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 16:
1390 divided by 907 is 1 with a remainder of 483.
The number 1 becomes the next digit in our result. 
Result so far: 75465.60970231
Subtract 907 from 1390 to get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

After the division, we end up with 75465.60970231 and a remainder of 4.83e-07.
