84920321 ÷ 458 
We want to figure out the number of times 84920321 can be divided by 458.

Let's proceed to step 1:
458 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 458

Going ahead to step 2:
458 goes into 84 0 times with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 458

On to step 3:
849 divided by 458 is 1 with a remainder of 391.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 458 from 849 leaves us with 391.
Append the next digit (2) from the dividend to 391 and continue with: 3912 / 458

On to step 4:
The number 458 fits into 3912 8 times, leaving a remainder of 248.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 3664 away from 3912, we end up with 248.
Bring next digit (0) of the dividend behind the 248 and repeat the process: 2480 / 458

Let's proceed to step 5:
If we divide 2480 by 458, we get 5 and a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
The remainder is 190 after subtracting 2290 from 2480.
Fetch the next digit (3) from the dividend, attach it to 190 and continue: 1903 / 458

On to step 6:
The number 458 fits into 1903 4 times, leaving a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 1854.0
Subtracting 1832 from 1903 leaves us with 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 458

Moving on to step 7:
458 can be fit into 712 1 times, resulting in a remainder of 254.
Record the quotient 1 as the next digit in the result. 
Result so far: 18541.0
The remainder is 254 after subtracting 458 from 712.
Bring next digit (1) of the dividend behind the 254 and repeat the process: 2541 / 458

Going ahead to step 8:
2541 divided by 458 is 5 with a remainder of 251.
Write down 5 as next digit of the result. 
Result so far: 185415.0
If we take 2290 away from 2541, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 9:
458 can be fit into 2510 5 times, resulting in a remainder of 220.
Write down 5 as next digit of the result. 
Result so far: 185415.5
The remainder is 220 after subtracting 2290 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
When dividing 2200 by 458, we get 4 with a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 185415.54
The remainder is 368 after subtracting 1832 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 11:
3680 divided by 458 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 185415.548
If we take 3664 away from 3680, 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.

Moving on to step 12:
160 divided by 458 is 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 185415.548
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
458 can be fit into 1600 3 times, resulting in a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 185415.54803
The remainder is 226 after subtracting 1374 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 14:
458 can be fit into 2260 4 times, resulting in a remainder of 428.
Use 4 as the next digit of our solution. 
Result so far: 185415.548034
Subtracting 1832 from 2260 leaves us 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.

Let's proceed to step 15:
The number 458 fits into 4280 9 times, leaving a remainder of 158.
Write down 9 as next digit of the result. 
Result so far: 185415.5480349
Subtract 4122 from 4280 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 16:
When dividing 1580 by 458, we get 3 with a remainder of 206.
Record the quotient 3 as the next digit in the result. 
Result so far: 185415.54803493
Subtract 1374 from 1580 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

The final result is 185415.54803493 with a remainder of 2.06e-07.
