Let's divide 86390663 by 112
We want to figure out the number of times 86390663 can be divided by 112.

Step 1:
8 divided by 112 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 112

On to step 2:
86 divided by 112 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 112

Going ahead to step 3:
If we divide 863 by 112, we get 7 and a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 784 from 863 and we're left with 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 112

Going ahead to step 4:
The number 112 fits into 799 7 times, leaving a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we subtract 784 from 799, we get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 112

Advancing to step 5:
The number 112 fits into 150 1 times, leaving a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 771.0
Subtract 112 from 150 to get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 112

Step 6:
If we divide 386 by 112, we get 3 and a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 7713.0
Deduct 336 from 386 and we're left with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 112

Advancing to step 7:
If we divide 506 by 112, we get 4 and a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 77134.0
Subtract 448 from 506 to get 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 112

Going ahead to step 8:
583 divided by 112 is 5 with a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 771345.0
If we take 560 away from 583, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
The number 112 fits into 230 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 771345.2
If we subtract 224 from 230, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
If we divide 60 by 112, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 771345.2
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
600 divided by 112 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 771345.205
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
112 goes into 400 3 times with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 771345.2053
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
If we divide 640 by 112, we get 5 and a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 771345.20535
If we subtract 560 from 640, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
When dividing 800 by 112, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 771345.205357
Deduct 784 from 800 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 15:
If we divide 160 by 112, we get 1 and a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 771345.2053571
The remainder is 48 after subtracting 112 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
The number 112 fits into 480 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 771345.20535714
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 771345.20535714 with a remainder of 3.2e-08.
