98898674 divided by 678 
We want to figure out the number of times 98898674 can be divided by 678.

On to step 1:
The number 678 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 678

Moving on to step 2:
The number 678 fits into 98 0 times, leaving a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Include the next digit (8) from the dividend after 98, then repeat: 988 / 678

Advancing to step 3:
988 divided by 678 is 1 with a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 678 from 988 to get 310.
Append the next digit (9) from the dividend to 310 and continue with: 3109 / 678

Going ahead to step 4:
When dividing 3109 by 678, we get 4 with a remainder of 397.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2712 from 3109, we get 397.
Bring next digit (8) of the dividend behind the 397 and repeat the process: 3978 / 678

Step 5:
When dividing 3978 by 678, we get 5 with a remainder of 588.
Use 5 as the next digit of our solution. 
Result so far: 145.0
If we take 3390 away from 3978, we end up with 588.
Append the next digit (6) from the dividend to 588 and continue with: 5886 / 678

Step 6:
When dividing 5886 by 678, we get 8 with a remainder of 462.
The number 8 becomes the next digit in our result. 
Result so far: 1458.0
The remainder is 462 after subtracting 5424 from 5886.
Append the next digit (7) from the dividend to 462 and continue with: 4627 / 678

On to step 7:
The number 678 fits into 4627 6 times, leaving a remainder of 559.
Record the quotient 6 as the next digit in the result. 
Result so far: 14586.0
Subtracting 4068 from 4627 leaves us with 559.
Grab the next digit (4) from the dividend, add it to 559, then carry on: 5594 / 678

Let's proceed to step 8:
If we divide 5594 by 678, we get 8 and a remainder of 170.
The next digit of our result is 8. 
Result so far: 145868.0
Deduct 5424 from 5594 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 9:
678 can be fit into 1700 2 times, resulting in a remainder of 344.
The next digit of our result is 2. 
Result so far: 145868.2
If we take 1356 away from 1700, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 10:
678 can be fit into 3440 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 145868.25
Subtract 3390 from 3440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
When dividing 500 by 678, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 145868.25
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
678 goes into 5000 7 times with a remainder of 254.
Put 7 as the next digit of the answer. 
Result so far: 145868.2507
The remainder is 254 after subtracting 4746 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 13:
When dividing 2540 by 678, we get 3 with a remainder of 506.
Put 3 as the next digit of the answer. 
Result so far: 145868.25073
If we take 2034 away from 2540, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 14:
The number 678 fits into 5060 7 times, leaving a remainder of 314.
Write down 7 as next digit of the result. 
Result so far: 145868.250737
Subtracting 4746 from 5060 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 15:
The number 678 fits into 3140 4 times, leaving a remainder of 428.
Write down 4 as next digit of the result. 
Result so far: 145868.2507374
Deduct 2712 from 3140 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 16:
678 goes into 4280 6 times with a remainder of 212.
The next digit of our result is 6. 
Result so far: 145868.25073746
The remainder is 212 after subtracting 4068 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final outcome is 145868.25073746, with a leftover of 2.12e-07.
