81539493 ÷ 359 
Let's see how many times 359 fits into 81539493.

Step 1:
If we divide 8 by 359, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 359

Let's proceed to step 2:
81 divided by 359 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 359

Going ahead to step 3:
When dividing 815 by 359, we get 2 with a remainder of 97.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 718 from 815 leaves us with 97.
Take the next digit (3) from the dividend and append it to 97, then repeat: 973 / 359

Going ahead to step 4:
The number 359 fits into 973 2 times, leaving a remainder of 255.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 718 from 973 and we're left with 255.
Grab the next digit (9) from the dividend, add it to 255, then carry on: 2559 / 359

Step 5:
359 can be fit into 2559 7 times, resulting in a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
If we take 2513 away from 2559, we end up with 46.
Include the next digit (4) from the dividend after 46, then repeat: 464 / 359

Moving on to step 6:
359 goes into 464 1 times with a remainder of 105.
The next digit of our result is 1. 
Result so far: 2271.0
If we take 359 away from 464, we end up with 105.
Take the next digit (9) from the dividend and append it to 105, then repeat: 1059 / 359

On to step 7:
When dividing 1059 by 359, we get 2 with a remainder of 341.
Write down 2 as next digit of the result. 
Result so far: 22712.0
If we take 718 away from 1059, we end up with 341.
Grab the next digit (3) from the dividend, add it to 341, then carry on: 3413 / 359

Advancing to step 8:
If we divide 3413 by 359, we get 9 and a remainder of 182.
Record the quotient 9 as the next digit in the result. 
Result so far: 227129.0
If we subtract 3231 from 3413, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 9:
359 goes into 1820 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 227129.5
Subtract 1795 from 1820 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
250 divided by 359 is 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 227129.5
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 11:
If we divide 2500 by 359, we get 6 and a remainder of 346.
Put 6 as the next digit of the answer. 
Result so far: 227129.506
Deduct 2154 from 2500 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 12:
3460 divided by 359 is 9 with a remainder of 229.
The next digit of our result is 9. 
Result so far: 227129.5069
If we subtract 3231 from 3460, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 13:
359 can be fit into 2290 6 times, resulting in a remainder of 136.
The next digit of our result is 6. 
Result so far: 227129.50696
Subtract 2154 from 2290 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 14:
When dividing 1360 by 359, we get 3 with a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 227129.506963
Deduct 1077 from 1360 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 15:
The number 359 fits into 2830 7 times, leaving a remainder of 317.
Record the quotient 7 as the next digit in the result. 
Result so far: 227129.5069637
If we subtract 2513 from 2830, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 16:
When dividing 3170 by 359, we get 8 with a remainder of 298.
The next digit of our result is 8. 
Result so far: 227129.50696378
If we subtract 2872 from 3170, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Our division results in 227129.50696378 with a remaining 2.98e-07.
