21783487 ÷ 359 
We want to figure out the number of times 21783487 can be divided by 359.

Moving on to step 1:
2 divided by 359 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 359

Moving on to step 2:
The number 359 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 359

Going ahead to step 3:
217 divided by 359 is 0 with a remainder of 217.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Bring next digit (8) of the dividend behind the 217 and repeat the process: 2178 / 359

Going ahead to step 4:
359 can be fit into 2178 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 2154 from 2178 to get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 359

Advancing to step 5:
243 divided by 359 is 0 with a remainder of 243.
Use 0 as the next digit of our solution. 
Result so far: 60.0
If we take 0 away from 243, we end up with 243.
Append the next digit (4) from the dividend to 243 and continue with: 2434 / 359

Step 6:
359 can be fit into 2434 6 times, resulting in a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 606.0
Deduct 2154 from 2434 and we're left with 280.
Take the next digit (8) from the dividend and append it to 280, then repeat: 2808 / 359

Let's proceed to step 7:
When dividing 2808 by 359, we get 7 with a remainder of 295.
Use 7 as the next digit of our solution. 
Result so far: 6067.0
Deduct 2513 from 2808 and we're left with 295.
Include the next digit (7) from the dividend after 295, then repeat: 2957 / 359

Step 8:
If we divide 2957 by 359, we get 8 and a remainder of 85.
Record the quotient 8 as the next digit in the result. 
Result so far: 60678.0
Subtract 2872 from 2957 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
If we divide 850 by 359, we get 2 and a remainder of 132.
The next digit of our result is 2. 
Result so far: 60678.2
If we take 718 away from 850, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 10:
If we divide 1320 by 359, we get 3 and a remainder of 243.
The next digit of our result is 3. 
Result so far: 60678.23
The remainder is 243 after subtracting 1077 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 11:
359 goes into 2430 6 times with a remainder of 276.
Use 6 as the next digit of our solution. 
Result so far: 60678.236
The remainder is 276 after subtracting 2154 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 12:
The number 359 fits into 2760 7 times, leaving a remainder of 247.
The next digit of our result is 7. 
Result so far: 60678.2367
If we take 2513 away from 2760, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 13:
359 goes into 2470 6 times with a remainder of 316.
Write down 6 as next digit of the result. 
Result so far: 60678.23676
Deduct 2154 from 2470 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 14:
3160 divided by 359 is 8 with a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 60678.236768
If we take 2872 away from 3160, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 15:
359 goes into 2880 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 60678.2367688
Deduct 2872 from 2880 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 60678.2367688, with a leftover of 8e-08.
