80613874 ÷ 912 
Our goal is to divide 80613874 by 912.

Going ahead to step 1:
8 divided by 912 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 912

Advancing to step 2:
912 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 912

Let's proceed to step 3:
If we divide 806 by 912, we get 0 and a remainder of 806.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 806, we end up with 806.
Bring next digit (1) of the dividend behind the 806 and repeat the process: 8061 / 912

Advancing to step 4:
8061 divided by 912 is 8 with a remainder of 765.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 7296 from 8061 and we're left with 765.
Append the next digit (3) from the dividend to 765 and continue with: 7653 / 912

Going ahead to step 5:
The number 912 fits into 7653 8 times, leaving a remainder of 357.
Use 8 as the next digit of our solution. 
Result so far: 88.0
If we take 7296 away from 7653, we end up with 357.
Bring next digit (8) of the dividend behind the 357 and repeat the process: 3578 / 912

On to step 6:
3578 divided by 912 is 3 with a remainder of 842.
Record the quotient 3 as the next digit in the result. 
Result so far: 883.0
If we take 2736 away from 3578, we end up with 842.
Fetch the next digit (7) from the dividend, attach it to 842 and continue: 8427 / 912

On to step 7:
912 goes into 8427 9 times with a remainder of 219.
Write down 9 as next digit of the result. 
Result so far: 8839.0
If we take 8208 away from 8427, we end up with 219.
Append the next digit (4) from the dividend to 219 and continue with: 2194 / 912

On to step 8:
912 goes into 2194 2 times with a remainder of 370.
The number 2 becomes the next digit in our result. 
Result so far: 88392.0
The remainder is 370 after subtracting 1824 from 2194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 9:
If we divide 3700 by 912, we get 4 and a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 88392.4
Subtracting 3648 from 3700 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
912 goes into 520 0 times with a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 88392.4
Subtract 0 from 520 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 11:
912 can be fit into 5200 5 times, resulting in a remainder of 640.
Put 5 as the next digit of the answer. 
Result so far: 88392.405
Subtract 4560 from 5200 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 12:
When dividing 6400 by 912, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 88392.4057
The remainder is 16 after subtracting 6384 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 912 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 88392.4057
Deduct 0 from 160 and we're left 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.

Going ahead to step 14:
1600 divided by 912 is 1 with a remainder of 688.
The number 1 becomes the next digit in our result. 
Result so far: 88392.405701
Subtracting 912 from 1600 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 15:
912 can be fit into 6880 7 times, resulting in a remainder of 496.
The number 7 becomes the next digit in our result. 
Result so far: 88392.4057017
If we take 6384 away from 6880, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 16:
When dividing 4960 by 912, we get 5 with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 88392.40570175
Deduct 4560 from 4960 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 88392.40570175, and the remainder is 4e-07.
