90678863 ÷ 462 
We want to divide 90678863 by 462.

On to step 1:
9 divided by 462 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 462

Step 2:
90 divided by 462 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 462

Step 3:
If we divide 906 by 462, we get 1 and a remainder of 444.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 462 from 906, we get 444.
Fetch the next digit (7) from the dividend, attach it to 444 and continue: 4447 / 462

Advancing to step 4:
When dividing 4447 by 462, we get 9 with a remainder of 289.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 289 after subtracting 4158 from 4447.
Take the next digit (8) from the dividend and append it to 289, then repeat: 2898 / 462

Let's proceed to step 5:
If we divide 2898 by 462, we get 6 and a remainder of 126.
The next digit of our result is 6. 
Result so far: 196.0
If we take 2772 away from 2898, we end up with 126.
Include the next digit (8) from the dividend after 126, then repeat: 1268 / 462

Moving on to step 6:
462 goes into 1268 2 times with a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 1962.0
If we subtract 924 from 1268, we get 344.
Grab the next digit (6) from the dividend, add it to 344, then carry on: 3446 / 462

Let's proceed to step 7:
462 can be fit into 3446 7 times, resulting in a remainder of 212.
The number 7 becomes the next digit in our result. 
Result so far: 19627.0
If we take 3234 away from 3446, we end up with 212.
Append the next digit (3) from the dividend to 212 and continue with: 2123 / 462

On to step 8:
2123 divided by 462 is 4 with a remainder of 275.
Write down 4 as next digit of the result. 
Result so far: 196274.0
Deduct 1848 from 2123 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 9:
If we divide 2750 by 462, we get 5 and a remainder of 440.
The number 5 becomes the next digit in our result. 
Result so far: 196274.5
The remainder is 440 after subtracting 2310 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 10:
The number 462 fits into 4400 9 times, leaving a remainder of 242.
The number 9 becomes the next digit in our result. 
Result so far: 196274.59
Subtract 4158 from 4400 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 11:
When dividing 2420 by 462, we get 5 with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 196274.595
Subtracting 2310 from 2420 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 12:
1100 divided by 462 is 2 with a remainder of 176.
Write down 2 as next digit of the result. 
Result so far: 196274.5952
Subtracting 924 from 1100 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 13:
If we divide 1760 by 462, we get 3 and a remainder of 374.
Put 3 as the next digit of the answer. 
Result so far: 196274.59523
Subtract 1386 from 1760 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 14:
462 goes into 3740 8 times with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 196274.595238
If we take 3696 away from 3740, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 15:
The number 462 fits into 440 0 times, leaving a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 196274.595238
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 16:
4400 divided by 462 is 9 with a remainder of 242.
Record the quotient 9 as the next digit in the result. 
Result so far: 196274.59523809
The remainder is 242 after subtracting 4158 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final outcome is 196274.59523809, with a leftover of 2.42e-07.
