We look at the division of 77289273 by 907 
We want to figure out the number of times 77289273 can be divided by 907.

Step 1:
907 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 907

Moving on to step 2:
When dividing 77 by 907, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 907

Moving on to step 3:
907 goes into 772 0 times with a remainder of 772.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 772 after subtracting 0 from 772.
Bring next digit (8) of the dividend behind the 772 and repeat the process: 7728 / 907

Let's proceed to step 4:
907 goes into 7728 8 times with a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7256 from 7728 to get 472.
Fetch the next digit (9) from the dividend, attach it to 472 and continue: 4729 / 907

Moving on to step 5:
When dividing 4729 by 907, we get 5 with a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we subtract 4535 from 4729, we get 194.
Bring next digit (2) of the dividend behind the 194 and repeat the process: 1942 / 907

Step 6:
1942 divided by 907 is 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 852.0
Subtract 1814 from 1942 to get 128.
Bring next digit (7) of the dividend behind the 128 and repeat the process: 1287 / 907

Step 7:
The number 907 fits into 1287 1 times, leaving a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 8521.0
Subtract 907 from 1287 to get 380.
Bring next digit (3) of the dividend behind the 380 and repeat the process: 3803 / 907

Step 8:
907 goes into 3803 4 times with a remainder of 175.
The next digit of our result is 4. 
Result so far: 85214.0
If we subtract 3628 from 3803, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 9:
907 can be fit into 1750 1 times, resulting in a remainder of 843.
Record the quotient 1 as the next digit in the result. 
Result so far: 85214.1
Subtracting 907 from 1750 leaves us with 843.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8430, and continue the process.

Advancing to step 10:
907 goes into 8430 9 times with a remainder of 267.
The next digit of our result is 9. 
Result so far: 85214.19
Subtract 8163 from 8430 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 11:
When dividing 2670 by 907, we get 2 with a remainder of 856.
The number 2 becomes the next digit in our result. 
Result so far: 85214.192
If we take 1814 away from 2670, we end up with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Going ahead to step 12:
If we divide 8560 by 907, we get 9 and a remainder of 397.
Record the quotient 9 as the next digit in the result. 
Result so far: 85214.1929
The remainder is 397 after subtracting 8163 from 8560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Let's proceed to step 13:
If we divide 3970 by 907, we get 4 and a remainder of 342.
The number 4 becomes the next digit in our result. 
Result so far: 85214.19294
The remainder is 342 after subtracting 3628 from 3970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 14:
If we divide 3420 by 907, we get 3 and a remainder of 699.
Write down 3 as next digit of the result. 
Result so far: 85214.192943
The remainder is 699 after subtracting 2721 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Going ahead to step 15:
6990 divided by 907 is 7 with a remainder of 641.
The number 7 becomes the next digit in our result. 
Result so far: 85214.1929437
Deduct 6349 from 6990 and we're left with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Going ahead to step 16:
When dividing 6410 by 907, we get 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 85214.19294377
Subtracting 6349 from 6410 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The quotient of the division is 85214.19294377, and the remainder is 6.1e-08.
