We're dividing 98777891 by 424 
Let's see how many times 424 fits into 98777891.

Going ahead to step 1:
If we divide 9 by 424, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 424

On to step 2:
424 goes into 98 0 times with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 424

Going ahead to step 3:
When dividing 987 by 424, we get 2 with a remainder of 139.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 848 from 987 leaves us with 139.
Bring next digit (7) of the dividend behind the 139 and repeat the process: 1397 / 424

Advancing to step 4:
424 goes into 1397 3 times with a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 1272 from 1397 and we're left with 125.
Grab the next digit (7) from the dividend, add it to 125, then carry on: 1257 / 424

Step 5:
When dividing 1257 by 424, we get 2 with a remainder of 409.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
The remainder is 409 after subtracting 848 from 1257.
Take the next digit (8) from the dividend and append it to 409, then repeat: 4098 / 424

Moving on to step 6:
424 goes into 4098 9 times with a remainder of 282.
Record the quotient 9 as the next digit in the result. 
Result so far: 2329.0
Subtract 3816 from 4098 to get 282.
Fetch the next digit (9) from the dividend, attach it to 282 and continue: 2829 / 424

Advancing to step 7:
When dividing 2829 by 424, we get 6 with a remainder of 285.
Put 6 as the next digit of the answer. 
Result so far: 23296.0
If we take 2544 away from 2829, we end up with 285.
Grab the next digit (1) from the dividend, add it to 285, then carry on: 2851 / 424

Advancing to step 8:
424 goes into 2851 6 times with a remainder of 307.
Put 6 as the next digit of the answer. 
Result so far: 232966.0
Subtract 2544 from 2851 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 9:
The number 424 fits into 3070 7 times, leaving a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 232966.7
If we subtract 2968 from 3070, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
If we divide 1020 by 424, we get 2 and a remainder of 172.
The number 2 becomes the next digit in our result. 
Result so far: 232966.72
Deduct 848 from 1020 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 11:
424 can be fit into 1720 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 232966.724
Subtracting 1696 from 1720 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
The number 424 fits into 240 0 times, leaving a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 232966.724
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
424 can be fit into 2400 5 times, resulting in a remainder of 280.
The next digit of our result is 5. 
Result so far: 232966.72405
Subtracting 2120 from 2400 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 14:
The number 424 fits into 2800 6 times, leaving a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 232966.724056
Subtracting 2544 from 2800 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 15:
2560 divided by 424 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 232966.7240566
If we take 2544 away from 2560, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 232966.7240566, with a leftover of 1.6e-07.
