48688139 ÷ 905 
We're looking to find how many times 905 goes into 48688139.

Advancing to step 1:
When dividing 4 by 905, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 905

Moving on to step 2:
48 divided by 905 is 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 905

On to step 3:
905 can be fit into 486 0 times, resulting in a remainder of 486.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 486, we get 486.
Append the next digit (8) from the dividend to 486 and continue with: 4868 / 905

Going ahead to step 4:
When dividing 4868 by 905, we get 5 with a remainder of 343.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 343 after subtracting 4525 from 4868.
Append the next digit (8) from the dividend to 343 and continue with: 3438 / 905

Advancing to step 5:
905 can be fit into 3438 3 times, resulting in a remainder of 723.
Put 3 as the next digit of the answer. 
Result so far: 53.0
If we subtract 2715 from 3438, we get 723.
Bring next digit (1) of the dividend behind the 723 and repeat the process: 7231 / 905

Advancing to step 6:
If we divide 7231 by 905, we get 7 and a remainder of 896.
Put 7 as the next digit of the answer. 
Result so far: 537.0
Subtract 6335 from 7231 to get 896.
Bring next digit (3) of the dividend behind the 896 and repeat the process: 8963 / 905

Moving on to step 7:
When dividing 8963 by 905, we get 9 with a remainder of 818.
Write down 9 as next digit of the result. 
Result so far: 5379.0
Deduct 8145 from 8963 and we're left with 818.
Append the next digit (9) from the dividend to 818 and continue with: 8189 / 905

Advancing to step 8:
8189 divided by 905 is 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 53799.0
The remainder is 44 after subtracting 8145 from 8189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
The number 905 fits into 440 0 times, leaving a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 53799.0
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 10:
The number 905 fits into 4400 4 times, leaving a remainder of 780.
Use 4 as the next digit of our solution. 
Result so far: 53799.04
Deduct 3620 from 4400 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Let's proceed to step 11:
When dividing 7800 by 905, we get 8 with a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 53799.048
If we take 7240 away from 7800, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 12:
5600 divided by 905 is 6 with a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 53799.0486
Deduct 5430 from 5600 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 13:
905 can be fit into 1700 1 times, resulting in a remainder of 795.
Write down 1 as next digit of the result. 
Result so far: 53799.04861
Subtracting 905 from 1700 leaves us with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

On to step 14:
If we divide 7950 by 905, we get 8 and a remainder of 710.
The number 8 becomes the next digit in our result. 
Result so far: 53799.048618
Subtract 7240 from 7950 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 15:
905 goes into 7100 7 times with a remainder of 765.
Put 7 as the next digit of the answer. 
Result so far: 53799.0486187
If we subtract 6335 from 7100, we get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Step 16:
905 can be fit into 7650 8 times, resulting in a remainder of 410.
Put 8 as the next digit of the answer. 
Result so far: 53799.04861878
If we take 7240 away from 7650, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final result is 53799.04861878 with a remainder of 4.1e-07.
