Let's divide 89589970 by 678
We want to figure out the number of times 89589970 can be divided by 678.

On to step 1:
8 divided by 678 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 678

On to step 2:
If we divide 89 by 678, we get 0 and a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Grab the next digit (5) from the dividend, add it to 89, then carry on: 895 / 678

Advancing to step 3:
895 divided by 678 is 1 with a remainder of 217.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 217 after subtracting 678 from 895.
Include the next digit (8) from the dividend after 217, then repeat: 2178 / 678

Advancing to step 4:
2178 divided by 678 is 3 with a remainder of 144.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 2034 from 2178, we get 144.
Grab the next digit (9) from the dividend, add it to 144, then carry on: 1449 / 678

Step 5:
The number 678 fits into 1449 2 times, leaving a remainder of 93.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we take 1356 away from 1449, we end up with 93.
Grab the next digit (9) from the dividend, add it to 93, then carry on: 939 / 678

On to step 6:
678 goes into 939 1 times with a remainder of 261.
The next digit of our result is 1. 
Result so far: 1321.0
Subtract 678 from 939 to get 261.
Fetch the next digit (7) from the dividend, attach it to 261 and continue: 2617 / 678

Advancing to step 7:
If we divide 2617 by 678, we get 3 and a remainder of 583.
Write down 3 as next digit of the result. 
Result so far: 13213.0
The remainder is 583 after subtracting 2034 from 2617.
Include the next digit (0) from the dividend after 583, then repeat: 5830 / 678

Going ahead to step 8:
678 can be fit into 5830 8 times, resulting in a remainder of 406.
Record the quotient 8 as the next digit in the result. 
Result so far: 132138.0
Subtract 5424 from 5830 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 9:
The number 678 fits into 4060 5 times, leaving a remainder of 670.
Use 5 as the next digit of our solution. 
Result so far: 132138.5
Subtract 3390 from 4060 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 10:
If we divide 6700 by 678, we get 9 and a remainder of 598.
The number 9 becomes the next digit in our result. 
Result so far: 132138.59
Subtract 6102 from 6700 to get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 11:
678 can be fit into 5980 8 times, resulting in a remainder of 556.
Record the quotient 8 as the next digit in the result. 
Result so far: 132138.598
The remainder is 556 after subtracting 5424 from 5980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 12:
5560 divided by 678 is 8 with a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 132138.5988
If we subtract 5424 from 5560, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 132138.5988 and a remainder of 0.00136.
