57390730 ÷ 905 
We want to figure out the number of times 57390730 can be divided by 905.

On to step 1:
When dividing 5 by 905, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 905

Step 2:
When dividing 57 by 905, we get 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 905

On to step 3:
573 divided by 905 is 0 with a remainder of 573.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 573, we get 573.
Bring next digit (9) of the dividend behind the 573 and repeat the process: 5739 / 905

Step 4:
If we divide 5739 by 905, we get 6 and a remainder of 309.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 5430 from 5739 and we're left with 309.
Include the next digit (0) from the dividend after 309, then repeat: 3090 / 905

Moving on to step 5:
905 goes into 3090 3 times with a remainder of 375.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we subtract 2715 from 3090, we get 375.
Fetch the next digit (7) from the dividend, attach it to 375 and continue: 3757 / 905

Going ahead to step 6:
905 can be fit into 3757 4 times, resulting in a remainder of 137.
Put 4 as the next digit of the answer. 
Result so far: 634.0
If we take 3620 away from 3757, we end up with 137.
Include the next digit (3) from the dividend after 137, then repeat: 1373 / 905

Step 7:
The number 905 fits into 1373 1 times, leaving a remainder of 468.
The next digit of our result is 1. 
Result so far: 6341.0
If we take 905 away from 1373, we end up with 468.
Append the next digit (0) from the dividend to 468 and continue with: 4680 / 905

Moving on to step 8:
When dividing 4680 by 905, we get 5 with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 63415.0
Subtract 4525 from 4680 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
905 can be fit into 1550 1 times, resulting in a remainder of 645.
The number 1 becomes the next digit in our result. 
Result so far: 63415.1
If we subtract 905 from 1550, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Step 10:
905 goes into 6450 7 times with a remainder of 115.
The number 7 becomes the next digit in our result. 
Result so far: 63415.17
If we subtract 6335 from 6450, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 11:
1150 divided by 905 is 1 with a remainder of 245.
Write down 1 as next digit of the result. 
Result so far: 63415.171
Deduct 905 from 1150 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 12:
When dividing 2450 by 905, we get 2 with a remainder of 640.
Write down 2 as next digit of the result. 
Result so far: 63415.1712
If we take 1810 away from 2450, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
6400 divided by 905 is 7 with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 63415.17127
Deduct 6335 from 6400 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 14:
905 can be fit into 650 0 times, resulting in a remainder of 650.
Use 0 as the next digit of our solution. 
Result so far: 63415.17127
Deduct 0 from 650 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 15:
905 goes into 6500 7 times with a remainder of 165.
The number 7 becomes the next digit in our result. 
Result so far: 63415.1712707
Deduct 6335 from 6500 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 16:
905 can be fit into 1650 1 times, resulting in a remainder of 745.
Record the quotient 1 as the next digit in the result. 
Result so far: 63415.17127071
Deduct 905 from 1650 and we're left with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

The final result is 63415.17127071 with a remainder of 7.45e-07.
