78983548 ÷ 859 
Our goal is to divide 78983548 by 859.

Moving on to step 1:
859 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 859

Step 2:
If we divide 78 by 859, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 859

Going ahead to step 3:
When dividing 789 by 859, we get 0 with a remainder of 789.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 789 and we're left with 789.
Grab the next digit (8) from the dividend, add it to 789, then carry on: 7898 / 859

Going ahead to step 4:
If we divide 7898 by 859, we get 9 and a remainder of 167.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 7731 from 7898 to get 167.
Grab the next digit (3) from the dividend, add it to 167, then carry on: 1673 / 859

Let's proceed to step 5:
859 goes into 1673 1 times with a remainder of 814.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we subtract 859 from 1673, we get 814.
Take the next digit (5) from the dividend and append it to 814, then repeat: 8145 / 859

Let's proceed to step 6:
The number 859 fits into 8145 9 times, leaving a remainder of 414.
The number 9 becomes the next digit in our result. 
Result so far: 919.0
Subtract 7731 from 8145 to get 414.
Grab the next digit (4) from the dividend, add it to 414, then carry on: 4144 / 859

Let's proceed to step 7:
If we divide 4144 by 859, we get 4 and a remainder of 708.
The number 4 becomes the next digit in our result. 
Result so far: 9194.0
Subtract 3436 from 4144 to get 708.
Bring next digit (8) of the dividend behind the 708 and repeat the process: 7088 / 859

Going ahead to step 8:
The number 859 fits into 7088 8 times, leaving a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 91948.0
If we subtract 6872 from 7088, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 9:
The number 859 fits into 2160 2 times, leaving a remainder of 442.
The number 2 becomes the next digit in our result. 
Result so far: 91948.2
If we take 1718 away from 2160, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Let's proceed to step 10:
When dividing 4420 by 859, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 91948.25
Subtracting 4295 from 4420 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 11:
1250 divided by 859 is 1 with a remainder of 391.
Write down 1 as next digit of the result. 
Result so far: 91948.251
Subtract 859 from 1250 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Let's proceed to step 12:
If we divide 3910 by 859, we get 4 and a remainder of 474.
The number 4 becomes the next digit in our result. 
Result so far: 91948.2514
If we subtract 3436 from 3910, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 13:
If we divide 4740 by 859, we get 5 and a remainder of 445.
Put 5 as the next digit of the answer. 
Result so far: 91948.25145
If we take 4295 away from 4740, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 14:
859 goes into 4450 5 times with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 91948.251455
Deduct 4295 from 4450 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

After the division, we end up with 91948.251455 and a remainder of 1.55e-05.
