90486494 ÷ 308 
Let's see how many times 308 fits into 90486494.

Let's proceed to step 1:
308 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 308

Advancing to step 2:
308 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Append the next digit (4) from the dividend to 90 and continue with: 904 / 308

On to step 3:
If we divide 904 by 308, we get 2 and a remainder of 288.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 616 away from 904, we end up with 288.
Bring next digit (8) of the dividend behind the 288 and repeat the process: 2888 / 308

On to step 4:
308 can be fit into 2888 9 times, resulting in a remainder of 116.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtract 2772 from 2888 to get 116.
Append the next digit (6) from the dividend to 116 and continue with: 1166 / 308

Step 5:
The number 308 fits into 1166 3 times, leaving a remainder of 242.
Write down 3 as next digit of the result. 
Result so far: 293.0
Subtract 924 from 1166 to get 242.
Include the next digit (4) from the dividend after 242, then repeat: 2424 / 308

Advancing to step 6:
If we divide 2424 by 308, we get 7 and a remainder of 268.
Use 7 as the next digit of our solution. 
Result so far: 2937.0
If we take 2156 away from 2424, we end up with 268.
Bring next digit (9) of the dividend behind the 268 and repeat the process: 2689 / 308

Advancing to step 7:
2689 divided by 308 is 8 with a remainder of 225.
Put 8 as the next digit of the answer. 
Result so far: 29378.0
If we subtract 2464 from 2689, we get 225.
Append the next digit (4) from the dividend to 225 and continue with: 2254 / 308

Step 8:
308 goes into 2254 7 times with a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 293787.0
Deduct 2156 from 2254 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 9:
980 divided by 308 is 3 with a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 293787.3
Subtracting 924 from 980 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
560 divided by 308 is 1 with a remainder of 252.
Use 1 as the next digit of our solution. 
Result so far: 293787.31
If we subtract 308 from 560, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 11:
If we divide 2520 by 308, we get 8 and a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 293787.318
If we take 2464 away from 2520, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
560 divided by 308 is 1 with a remainder of 252.
Record the quotient 1 as the next digit in the result. 
Result so far: 293787.3181
If we subtract 308 from 560, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 13:
When dividing 2520 by 308, we get 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 293787.31818
The remainder is 56 after subtracting 2464 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
When dividing 560 by 308, we get 1 with a remainder of 252.
Put 1 as the next digit of the answer. 
Result so far: 293787.318181
Subtract 308 from 560 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 15:
308 can be fit into 2520 8 times, resulting in a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 293787.3181818
Deduct 2464 from 2520 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 16:
308 can be fit into 560 1 times, resulting in a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 293787.31818181
Subtract 308 from 560 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final outcome is 293787.31818181, with a leftover of 2.52e-07.
