We look at the division of 77903457 by 907 
We want to divide 77903457 by 907.

Moving on to step 1:
7 divided by 907 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 907

Going ahead to step 2:
If we divide 77 by 907, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 907

Step 3:
If we divide 779 by 907, we get 0 and a remainder of 779.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 779, we get 779.
Take the next digit (0) from the dividend and append it to 779, then repeat: 7790 / 907

Advancing to step 4:
907 can be fit into 7790 8 times, resulting in a remainder of 534.
The next digit of our result is 8. 
Result so far: 8.0
If we take 7256 away from 7790, we end up with 534.
Include the next digit (3) from the dividend after 534, then repeat: 5343 / 907

Advancing to step 5:
If we divide 5343 by 907, we get 5 and a remainder of 808.
The next digit of our result is 5. 
Result so far: 85.0
Subtract 4535 from 5343 to get 808.
Include the next digit (4) from the dividend after 808, then repeat: 8084 / 907

Going ahead to step 6:
8084 divided by 907 is 8 with a remainder of 828.
Write down 8 as next digit of the result. 
Result so far: 858.0
Subtracting 7256 from 8084 leaves us with 828.
Take the next digit (5) from the dividend and append it to 828, then repeat: 8285 / 907

Moving on to step 7:
907 can be fit into 8285 9 times, resulting in a remainder of 122.
The number 9 becomes the next digit in our result. 
Result so far: 8589.0
If we subtract 8163 from 8285, we get 122.
Include the next digit (7) from the dividend after 122, then repeat: 1227 / 907

On to step 8:
The number 907 fits into 1227 1 times, leaving a remainder of 320.
The number 1 becomes the next digit in our result. 
Result so far: 85891.0
The remainder is 320 after subtracting 907 from 1227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 9:
907 goes into 3200 3 times with a remainder of 479.
Record the quotient 3 as the next digit in the result. 
Result so far: 85891.3
Deduct 2721 from 3200 and we're left with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Advancing to step 10:
907 goes into 4790 5 times with a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 85891.35
The remainder is 255 after subtracting 4535 from 4790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 11:
When dividing 2550 by 907, we get 2 with a remainder of 736.
The number 2 becomes the next digit in our result. 
Result so far: 85891.352
The remainder is 736 after subtracting 1814 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 12:
When dividing 7360 by 907, we get 8 with a remainder of 104.
The next digit of our result is 8. 
Result so far: 85891.3528
The remainder is 104 after subtracting 7256 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 13:
1040 divided by 907 is 1 with a remainder of 133.
Put 1 as the next digit of the answer. 
Result so far: 85891.35281
Subtract 907 from 1040 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 14:
The number 907 fits into 1330 1 times, leaving a remainder of 423.
Write down 1 as next digit of the result. 
Result so far: 85891.352811
If we take 907 away from 1330, we end up with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

The final outcome is 85891.352811, with a leftover of 4.23e-05.
