We divide 88639842 by 458
We want to divide 88639842 by 458.

Going ahead to step 1:
If we divide 8 by 458, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 458

Advancing to step 2:
The number 458 fits into 88 0 times, leaving a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Fetch the next digit (6) from the dividend, attach it to 88 and continue: 886 / 458

Moving on to step 3:
The number 458 fits into 886 1 times, leaving a remainder of 428.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 428 after subtracting 458 from 886.
Append the next digit (3) from the dividend to 428 and continue with: 4283 / 458

Advancing to step 4:
If we divide 4283 by 458, we get 9 and a remainder of 161.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 4122 from 4283, we get 161.
Grab the next digit (9) from the dividend, add it to 161, then carry on: 1619 / 458

Moving on to step 5:
458 can be fit into 1619 3 times, resulting in a remainder of 245.
The next digit of our result is 3. 
Result so far: 193.0
If we subtract 1374 from 1619, we get 245.
Fetch the next digit (8) from the dividend, attach it to 245 and continue: 2458 / 458

Advancing to step 6:
458 can be fit into 2458 5 times, resulting in a remainder of 168.
The number 5 becomes the next digit in our result. 
Result so far: 1935.0
The remainder is 168 after subtracting 2290 from 2458.
Bring next digit (4) of the dividend behind the 168 and repeat the process: 1684 / 458

Moving on to step 7:
If we divide 1684 by 458, we get 3 and a remainder of 310.
Write down 3 as next digit of the result. 
Result so far: 19353.0
Subtracting 1374 from 1684 leaves us with 310.
Take the next digit (2) from the dividend and append it to 310, then repeat: 3102 / 458

Moving on to step 8:
458 goes into 3102 6 times with a remainder of 354.
Put 6 as the next digit of the answer. 
Result so far: 193536.0
Subtracting 2748 from 3102 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 9:
3540 divided by 458 is 7 with a remainder of 334.
The next digit of our result is 7. 
Result so far: 193536.7
Deduct 3206 from 3540 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 10:
When dividing 3340 by 458, we get 7 with a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 193536.77
If we subtract 3206 from 3340, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

In conclusion, the division gives 193536.77 with a balance of 0.134.
