We divide 81501030 by 457
We want to figure out the number of times 81501030 can be divided by 457.

Let's proceed to step 1:
457 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 457

Let's proceed to step 2:
457 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 457

Step 3:
If we divide 815 by 457, we get 1 and a remainder of 358.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 457 from 815 and we're left with 358.
Fetch the next digit (0) from the dividend, attach it to 358 and continue: 3580 / 457

On to step 4:
457 can be fit into 3580 7 times, resulting in a remainder of 381.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 3199 away from 3580, we end up with 381.
Take the next digit (1) from the dividend and append it to 381, then repeat: 3811 / 457

Advancing to step 5:
457 goes into 3811 8 times with a remainder of 155.
The next digit of our result is 8. 
Result so far: 178.0
If we subtract 3656 from 3811, we get 155.
Append the next digit (0) from the dividend to 155 and continue with: 1550 / 457

Advancing to step 6:
When dividing 1550 by 457, we get 3 with a remainder of 179.
The next digit of our result is 3. 
Result so far: 1783.0
Subtracting 1371 from 1550 leaves us with 179.
Fetch the next digit (3) from the dividend, attach it to 179 and continue: 1793 / 457

On to step 7:
If we divide 1793 by 457, we get 3 and a remainder of 422.
Write down 3 as next digit of the result. 
Result so far: 17833.0
Subtract 1371 from 1793 to get 422.
Fetch the next digit (0) from the dividend, attach it to 422 and continue: 4220 / 457

Going ahead to step 8:
When dividing 4220 by 457, we get 9 with a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 178339.0
The remainder is 107 after subtracting 4113 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 9:
457 can be fit into 1070 2 times, resulting in a remainder of 156.
The next digit of our result is 2. 
Result so far: 178339.2
If we take 914 away from 1070, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 10:
1560 divided by 457 is 3 with a remainder of 189.
The next digit of our result is 3. 
Result so far: 178339.23
If we take 1371 away from 1560, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 11:
457 goes into 1890 4 times with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 178339.234
If we take 1828 away from 1890, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
If we divide 620 by 457, we get 1 and a remainder of 163.
Use 1 as the next digit of our solution. 
Result so far: 178339.2341
If we take 457 away from 620, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 13:
If we divide 1630 by 457, we get 3 and a remainder of 259.
Put 3 as the next digit of the answer. 
Result so far: 178339.23413
If we subtract 1371 from 1630, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 14:
457 can be fit into 2590 5 times, resulting in a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 178339.234135
Deduct 2285 from 2590 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 15:
The number 457 fits into 3050 6 times, leaving a remainder of 308.
Use 6 as the next digit of our solution. 
Result so far: 178339.2341356
Deduct 2742 from 3050 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 16:
3080 divided by 457 is 6 with a remainder of 338.
The next digit of our result is 6. 
Result so far: 178339.23413566
Deduct 2742 from 3080 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

The final outcome is 178339.23413566, with a leftover of 3.38e-07.
