77846139 ÷ 872 
Our goal is to divide 77846139 by 872.

Step 1:
The number 872 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 872

Moving on to step 2:
When dividing 77 by 872, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 872

Step 3:
872 goes into 778 0 times with a remainder of 778.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 778 and we're left with 778.
Grab the next digit (4) from the dividend, add it to 778, then carry on: 7784 / 872

Advancing to step 4:
The number 872 fits into 7784 8 times, leaving a remainder of 808.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 6976 from 7784 and we're left with 808.
Append the next digit (6) from the dividend to 808 and continue with: 8086 / 872

Step 5:
8086 divided by 872 is 9 with a remainder of 238.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtracting 7848 from 8086 leaves us with 238.
Bring next digit (1) of the dividend behind the 238 and repeat the process: 2381 / 872

Moving on to step 6:
872 can be fit into 2381 2 times, resulting in a remainder of 637.
Put 2 as the next digit of the answer. 
Result so far: 892.0
Subtract 1744 from 2381 to get 637.
Take the next digit (3) from the dividend and append it to 637, then repeat: 6373 / 872

Going ahead to step 7:
6373 divided by 872 is 7 with a remainder of 269.
The next digit of our result is 7. 
Result so far: 8927.0
If we subtract 6104 from 6373, we get 269.
Bring next digit (9) of the dividend behind the 269 and repeat the process: 2699 / 872

Moving on to step 8:
If we divide 2699 by 872, we get 3 and a remainder of 83.
The next digit of our result is 3. 
Result so far: 89273.0
Deduct 2616 from 2699 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 9:
When dividing 830 by 872, we get 0 with a remainder of 830.
Put 0 as the next digit of the answer. 
Result so far: 89273.0
Subtract 0 from 830 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

On to step 10:
When dividing 8300 by 872, we get 9 with a remainder of 452.
Use 9 as the next digit of our solution. 
Result so far: 89273.09
If we take 7848 away from 8300, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 11:
When dividing 4520 by 872, we get 5 with a remainder of 160.
Use 5 as the next digit of our solution. 
Result so far: 89273.095
Subtracting 4360 from 4520 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
1600 divided by 872 is 1 with a remainder of 728.
The number 1 becomes the next digit in our result. 
Result so far: 89273.0951
Subtract 872 from 1600 to get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Let's proceed to step 13:
If we divide 7280 by 872, we get 8 and a remainder of 304.
Put 8 as the next digit of the answer. 
Result so far: 89273.09518
Deduct 6976 from 7280 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 14:
If we divide 3040 by 872, we get 3 and a remainder of 424.
The next digit of our result is 3. 
Result so far: 89273.095183
If we subtract 2616 from 3040, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 15:
872 goes into 4240 4 times with a remainder of 752.
Record the quotient 4 as the next digit in the result. 
Result so far: 89273.0951834
If we take 3488 away from 4240, we end up with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Let's proceed to step 16:
7520 divided by 872 is 8 with a remainder of 544.
The next digit of our result is 8. 
Result so far: 89273.09518348
Subtracting 6976 from 7520 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The final result is 89273.09518348 with a remainder of 5.44e-07.
