We look at the division of 73217778 by 907 
We're looking to find how many times 907 goes into 73217778.

Advancing to step 1:
The number 907 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 907

Moving on to step 2:
907 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 907

Let's proceed to step 3:
732 divided by 907 is 0 with a remainder of 732.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 732, we end up with 732.
Take the next digit (1) from the dividend and append it to 732, then repeat: 7321 / 907

Let's proceed to step 4:
The number 907 fits into 7321 8 times, leaving a remainder of 65.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7256 from 7321 to get 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 907

Let's proceed to step 5:
657 divided by 907 is 0 with a remainder of 657.
The next digit of our result is 0. 
Result so far: 80.0
If we take 0 away from 657, we end up with 657.
Fetch the next digit (7) from the dividend, attach it to 657 and continue: 6577 / 907

Step 6:
907 can be fit into 6577 7 times, resulting in a remainder of 228.
Use 7 as the next digit of our solution. 
Result so far: 807.0
Subtract 6349 from 6577 to get 228.
Bring next digit (7) of the dividend behind the 228 and repeat the process: 2287 / 907

Step 7:
If we divide 2287 by 907, we get 2 and a remainder of 473.
Use 2 as the next digit of our solution. 
Result so far: 8072.0
The remainder is 473 after subtracting 1814 from 2287.
Append the next digit (8) from the dividend to 473 and continue with: 4738 / 907

Going ahead to step 8:
When dividing 4738 by 907, we get 5 with a remainder of 203.
Use 5 as the next digit of our solution. 
Result so far: 80725.0
Deduct 4535 from 4738 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 9:
If we divide 2030 by 907, we get 2 and a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 80725.2
Deduct 1814 from 2030 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 10:
907 goes into 2160 2 times with a remainder of 346.
Write down 2 as next digit of the result. 
Result so far: 80725.22
Deduct 1814 from 2160 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

In conclusion, the division gives 80725.22 with a balance of 0.346.
