21886410 ÷ 946 
Our goal is to divide 21886410 by 946.

Advancing to step 1:
If we divide 2 by 946, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 946

On to step 2:
946 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 946

Advancing to step 3:
When dividing 218 by 946, we get 0 with a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 218 to get 218.
Take the next digit (8) from the dividend and append it to 218, then repeat: 2188 / 946

Going ahead to step 4:
2188 divided by 946 is 2 with a remainder of 296.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1892 from 2188 to get 296.
Include the next digit (6) from the dividend after 296, then repeat: 2966 / 946

On to step 5:
When dividing 2966 by 946, we get 3 with a remainder of 128.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 128 after subtracting 2838 from 2966.
Take the next digit (4) from the dividend and append it to 128, then repeat: 1284 / 946

Going ahead to step 6:
When dividing 1284 by 946, we get 1 with a remainder of 338.
Record the quotient 1 as the next digit in the result. 
Result so far: 231.0
Subtracting 946 from 1284 leaves us with 338.
Grab the next digit (1) from the dividend, add it to 338, then carry on: 3381 / 946

Step 7:
3381 divided by 946 is 3 with a remainder of 543.
Record the quotient 3 as the next digit in the result. 
Result so far: 2313.0
If we take 2838 away from 3381, we end up with 543.
Include the next digit (0) from the dividend after 543, then repeat: 5430 / 946

Going ahead to step 8:
946 goes into 5430 5 times with a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 23135.0
Deduct 4730 from 5430 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 9:
7000 divided by 946 is 7 with a remainder of 378.
The number 7 becomes the next digit in our result. 
Result so far: 23135.7
Deduct 6622 from 7000 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 10:
946 goes into 3780 3 times with a remainder of 942.
The next digit of our result is 3. 
Result so far: 23135.73
Deduct 2838 from 3780 and we're left with 942.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9420, and continue the process.

Advancing to step 11:
The number 946 fits into 9420 9 times, leaving a remainder of 906.
Use 9 as the next digit of our solution. 
Result so far: 23135.739
The remainder is 906 after subtracting 8514 from 9420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9060, and continue the process.

Advancing to step 12:
946 can be fit into 9060 9 times, resulting in a remainder of 546.
The number 9 becomes the next digit in our result. 
Result so far: 23135.7399
Subtract 8514 from 9060 to get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

The quotient of the division is 23135.7399, and the remainder is 0.00546.
