53980210 divided by 697 
We want to figure out the number of times 53980210 can be divided by 697.

On to step 1:
5 divided by 697 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 697

Step 2:
If we divide 53 by 697, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 697

Going ahead to step 3:
697 can be fit into 539 0 times, resulting in a remainder of 539.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 539 leaves us with 539.
Fetch the next digit (8) from the dividend, attach it to 539 and continue: 5398 / 697

Step 4:
The number 697 fits into 5398 7 times, leaving a remainder of 519.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 4879 away from 5398, we end up with 519.
Grab the next digit (0) from the dividend, add it to 519, then carry on: 5190 / 697

Moving on to step 5:
When dividing 5190 by 697, we get 7 with a remainder of 311.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we subtract 4879 from 5190, we get 311.
Grab the next digit (2) from the dividend, add it to 311, then carry on: 3112 / 697

Moving on to step 6:
If we divide 3112 by 697, we get 4 and a remainder of 324.
The next digit of our result is 4. 
Result so far: 774.0
If we take 2788 away from 3112, we end up with 324.
Fetch the next digit (1) from the dividend, attach it to 324 and continue: 3241 / 697

Moving on to step 7:
3241 divided by 697 is 4 with a remainder of 453.
The next digit of our result is 4. 
Result so far: 7744.0
If we subtract 2788 from 3241, we get 453.
Append the next digit (0) from the dividend to 453 and continue with: 4530 / 697

Let's proceed to step 8:
4530 divided by 697 is 6 with a remainder of 348.
Record the quotient 6 as the next digit in the result. 
Result so far: 77446.0
Subtract 4182 from 4530 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
697 goes into 3480 4 times with a remainder of 692.
Write down 4 as next digit of the result. 
Result so far: 77446.4
Subtracting 2788 from 3480 leaves us with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Step 10:
When dividing 6920 by 697, we get 9 with a remainder of 647.
Record the quotient 9 as the next digit in the result. 
Result so far: 77446.49
Subtracting 6273 from 6920 leaves us with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Advancing to step 11:
When dividing 6470 by 697, we get 9 with a remainder of 197.
Use 9 as the next digit of our solution. 
Result so far: 77446.499
If we subtract 6273 from 6470, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The final outcome is 77446.499, with a leftover of 0.0197.
