43779879 ÷ 105 
We want to divide 43779879 by 105.

Going ahead to step 1:
105 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 105

On to step 2:
105 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 105

Step 3:
105 goes into 437 4 times with a remainder of 17.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 420 from 437 leaves us with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 105

Going ahead to step 4:
177 divided by 105 is 1 with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 105 away from 177, we end up with 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 105

Advancing to step 5:
729 divided by 105 is 6 with a remainder of 99.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
Subtract 630 from 729 to get 99.
Grab the next digit (8) from the dividend, add it to 99, then carry on: 998 / 105

On to step 6:
998 divided by 105 is 9 with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 4169.0
Deduct 945 from 998 and we're left with 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 105

Moving on to step 7:
105 can be fit into 537 5 times, resulting in a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 41695.0
The remainder is 12 after subtracting 525 from 537.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 105

On to step 8:
If we divide 129 by 105, we get 1 and a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 416951.0
If we take 105 away from 129, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
If we divide 240 by 105, we get 2 and a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 416951.2
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
105 goes into 300 2 times with a remainder of 90.
The next digit of our result is 2. 
Result so far: 416951.22
Subtracting 210 from 300 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 416951.22 with a remaining 0.09.
