78898973 ÷ 178 
Our goal is to divide 78898973 by 178.

Moving on to step 1:
178 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 178

Let's proceed to step 2:
If we divide 78 by 178, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 178

Moving on to step 3:
788 divided by 178 is 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 712 from 788 and we're left with 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 178

Going ahead to step 4:
178 can be fit into 769 4 times, resulting in a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 712 away from 769, we end up with 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 178

On to step 5:
178 goes into 578 3 times with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 443.0
Deduct 534 from 578 and we're left with 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 178

Let's proceed to step 6:
449 divided by 178 is 2 with a remainder of 93.
The next digit of our result is 2. 
Result so far: 4432.0
The remainder is 93 after subtracting 356 from 449.
Append the next digit (7) from the dividend to 93 and continue with: 937 / 178

Moving on to step 7:
The number 178 fits into 937 5 times, leaving a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 44325.0
Deduct 890 from 937 and we're left with 47.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 178

Moving on to step 8:
473 divided by 178 is 2 with a remainder of 117.
The next digit of our result is 2. 
Result so far: 443252.0
If we subtract 356 from 473, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
When dividing 1170 by 178, we get 6 with a remainder of 102.
Put 6 as the next digit of the answer. 
Result so far: 443252.6
The remainder is 102 after subtracting 1068 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
The number 178 fits into 1020 5 times, leaving a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 443252.65
The remainder is 130 after subtracting 890 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
The number 178 fits into 1300 7 times, leaving a remainder of 54.
The next digit of our result is 7. 
Result so far: 443252.657
Subtracting 1246 from 1300 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
If we divide 540 by 178, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 443252.6573
Subtracting 534 from 540 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
The number 178 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 443252.6573
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
If we divide 600 by 178, we get 3 and a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 443252.657303
Deduct 534 from 600 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 15:
If we divide 660 by 178, we get 3 and a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 443252.6573033
Deduct 534 from 660 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

After the division, we end up with 443252.6573033 and a remainder of 1.26e-06.
