21781861 divided by 46 
We're looking to find how many times 46 goes into 21781861.

On to step 1:
When dividing 2 by 46, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 46

On to step 2:
When dividing 21 by 46, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 46

Step 3:
46 goes into 217 4 times with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 184 away from 217, we end up with 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 46

On to step 4:
338 divided by 46 is 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 322 from 338, we get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 46

Step 5:
The number 46 fits into 161 3 times, leaving a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 473.0
If we subtract 138 from 161, we get 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 46

Moving on to step 6:
46 goes into 238 5 times with a remainder of 8.
The next digit of our result is 5. 
Result so far: 4735.0
Deduct 230 from 238 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 46

Let's proceed to step 7:
86 divided by 46 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 47351.0
If we subtract 46 from 86, we get 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 46

Moving on to step 8:
46 goes into 401 8 times with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 473518.0
Subtracting 368 from 401 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
When dividing 330 by 46, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 473518.7
The remainder is 8 after subtracting 322 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
The number 46 fits into 80 1 times, leaving a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 473518.71
If we take 46 away from 80, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
46 goes into 340 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 473518.717
The remainder is 18 after subtracting 322 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
180 divided by 46 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 473518.7173
Subtract 138 from 180 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
46 goes into 420 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 473518.71739
If we subtract 414 from 420, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
The number 46 fits into 60 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 473518.717391
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
When dividing 140 by 46, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 473518.7173913
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 16:
46 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 473518.7173913
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 473518.7173913, with a leftover of 2e-08.
