Step 5:
If we divide 5923 by 687, we get 8 and a remainder of 427.
Write down 8 as next digit of the result. 
Result so far: 118.0
Subtract 5496 from 5923 to get 427.
Grab the next digit (4) from the dividend, add it to 427, then carry on: 4274 / 687

Going ahead to step 6:
4274 divided by 687 is 6 with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 1186.0
The remainder is 152 after subtracting 4122 from 4274.
Grab the next digit (3) from the dividend, add it to 152, then carry on: 1523 / 687

Let's proceed to step 7:
When dividing 1523 by 687, we get 2 with a remainder of 149.
Use 2 as the next digit of our solution. 
Result so far: 11862.0
The remainder is 149 after subtracting 1374 from 1523.
Fetch the next digit (9) from the dividend, attach it to 149 and continue: 1499 / 687

Step 8:
1499 divided by 687 is 2 with a remainder of 125.
The next digit of our result is 2. 
Result so far: 118622.0
Subtract 1374 from 1499 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 9:
687 goes into 1250 1 times with a remainder of 563.
Put 1 as the next digit of the answer. 
Result so far: 118622.1
Subtract 687 from 1250 to get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Going ahead to step 10:
When dividing 5630 by 687, we get 8 with a remainder of 134.
Write down 8 as next digit of the result. 
Result so far: 118622.18
If we subtract 5496 from 5630, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 11:
The number 687 fits into 1340 1 times, leaving a remainder of 653.
The next digit of our result is 1. 
Result so far: 118622.181
Subtracting 687 from 1340 leaves us with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

On to step 12:
The number 687 fits into 6530 9 times, leaving a remainder of 347.
The next digit of our result is 9. 
Result so far: 118622.1819
Subtract 6183 from 6530 to get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Step 13:
If we divide 3470 by 687, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 118622.18195
If we take 3435 away from 3470, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
350 divided by 687 is 0 with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 118622.18195
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 15:
687 can be fit into 3500 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 118622.1819505
Subtract 3435 from 3500 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 16:
The number 687 fits into 650 0 times, leaving a remainder of 650.
The next digit of our result is 0. 
Result so far: 118622.1819505
Subtract 0 from 650 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

In conclusion, the division gives 118622.1819505 with a balance of 6.5e-07.
