We're dividing 78311591 by 672 
We're looking to find how many times 672 goes into 78311591.

Advancing to step 1:
The number 672 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 672

Going ahead to step 2:
672 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 672

On to step 3:
672 goes into 783 1 times with a remainder of 111.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 672 from 783 to get 111.
Fetch the next digit (1) from the dividend, attach it to 111 and continue: 1111 / 672

Moving on to step 4:
The number 672 fits into 1111 1 times, leaving a remainder of 439.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 672 from 1111 and we're left with 439.
Grab the next digit (1) from the dividend, add it to 439, then carry on: 4391 / 672

On to step 5:
672 goes into 4391 6 times with a remainder of 359.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Deduct 4032 from 4391 and we're left with 359.
Take the next digit (5) from the dividend and append it to 359, then repeat: 3595 / 672

Moving on to step 6:
The number 672 fits into 3595 5 times, leaving a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 1165.0
If we subtract 3360 from 3595, we get 235.
Take the next digit (9) from the dividend and append it to 235, then repeat: 2359 / 672

Let's proceed to step 7:
If we divide 2359 by 672, we get 3 and a remainder of 343.
The next digit of our result is 3. 
Result so far: 11653.0
Subtract 2016 from 2359 to get 343.
Fetch the next digit (1) from the dividend, attach it to 343 and continue: 3431 / 672

Going ahead to step 8:
3431 divided by 672 is 5 with a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 116535.0
Subtract 3360 from 3431 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
When dividing 710 by 672, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 116535.1
If we subtract 672 from 710, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
The number 672 fits into 380 0 times, leaving a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 116535.1
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 11:
If we divide 3800 by 672, we get 5 and a remainder of 440.
Put 5 as the next digit of the answer. 
Result so far: 116535.105
The remainder is 440 after subtracting 3360 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
672 goes into 4400 6 times with a remainder of 368.
Write down 6 as next digit of the result. 
Result so far: 116535.1056
Deduct 4032 from 4400 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 13:
When dividing 3680 by 672, we get 5 with a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 116535.10565
Subtract 3360 from 3680 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
672 can be fit into 3200 4 times, resulting in a remainder of 512.
The next digit of our result is 4. 
Result so far: 116535.105654
Subtract 2688 from 3200 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 15:
672 goes into 5120 7 times with a remainder of 416.
Put 7 as the next digit of the answer. 
Result so far: 116535.1056547
Subtract 4704 from 5120 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 16:
The number 672 fits into 4160 6 times, leaving a remainder of 128.
The next digit of our result is 6. 
Result so far: 116535.10565476
The remainder is 128 after subtracting 4032 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 116535.10565476, with a leftover of 1.28e-07.
