53509867 divided by 699 
We want to figure out the number of times 53509867 can be divided by 699.

Step 1:
699 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 699

Advancing to step 2:
699 goes into 53 0 times with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 699

Going ahead to step 3:
535 divided by 699 is 0 with a remainder of 535.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 535 after subtracting 0 from 535.
Fetch the next digit (0) from the dividend, attach it to 535 and continue: 5350 / 699

Moving on to step 4:
The number 699 fits into 5350 7 times, leaving a remainder of 457.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4893 away from 5350, we end up with 457.
Append the next digit (9) from the dividend to 457 and continue with: 4579 / 699

Advancing to step 5:
If we divide 4579 by 699, we get 6 and a remainder of 385.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 4194 from 4579, we get 385.
Append the next digit (8) from the dividend to 385 and continue with: 3858 / 699

Step 6:
699 can be fit into 3858 5 times, resulting in a remainder of 363.
Write down 5 as next digit of the result. 
Result so far: 765.0
If we subtract 3495 from 3858, we get 363.
Grab the next digit (6) from the dividend, add it to 363, then carry on: 3636 / 699

Step 7:
The number 699 fits into 3636 5 times, leaving a remainder of 141.
Put 5 as the next digit of the answer. 
Result so far: 7655.0
If we take 3495 away from 3636, we end up with 141.
Append the next digit (7) from the dividend to 141 and continue with: 1417 / 699

Moving on to step 8:
When dividing 1417 by 699, we get 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 76552.0
Subtracting 1398 from 1417 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
699 can be fit into 190 0 times, resulting in a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 76552.0
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
If we divide 1900 by 699, we get 2 and a remainder of 502.
Put 2 as the next digit of the answer. 
Result so far: 76552.02
If we subtract 1398 from 1900, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 11:
The number 699 fits into 5020 7 times, leaving a remainder of 127.
Put 7 as the next digit of the answer. 
Result so far: 76552.027
If we take 4893 away from 5020, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 12:
699 goes into 1270 1 times with a remainder of 571.
The number 1 becomes the next digit in our result. 
Result so far: 76552.0271
The remainder is 571 after subtracting 699 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Going ahead to step 13:
5710 divided by 699 is 8 with a remainder of 118.
Use 8 as the next digit of our solution. 
Result so far: 76552.02718
Deduct 5592 from 5710 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 14:
When dividing 1180 by 699, we get 1 with a remainder of 481.
Write down 1 as next digit of the result. 
Result so far: 76552.027181
Subtract 699 from 1180 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Going ahead to step 15:
4810 divided by 699 is 6 with a remainder of 616.
The number 6 becomes the next digit in our result. 
Result so far: 76552.0271816
Deduct 4194 from 4810 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Advancing to step 16:
When dividing 6160 by 699, we get 8 with a remainder of 568.
Use 8 as the next digit of our solution. 
Result so far: 76552.02718168
Deduct 5592 from 6160 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final result is 76552.02718168 with a remainder of 5.68e-07.
