We look at the division of 97787575 by 840 
We're looking to find how many times 840 goes into 97787575.

On to step 1:
840 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 840

Going ahead to step 2:
840 goes into 97 0 times with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Bring next digit (7) of the dividend behind the 97 and repeat the process: 977 / 840

Going ahead to step 3:
When dividing 977 by 840, we get 1 with a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 840 away from 977, we end up with 137.
Bring next digit (8) of the dividend behind the 137 and repeat the process: 1378 / 840

Let's proceed to step 4:
840 can be fit into 1378 1 times, resulting in a remainder of 538.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 538 after subtracting 840 from 1378.
Take the next digit (7) from the dividend and append it to 538, then repeat: 5387 / 840

Going ahead to step 5:
The number 840 fits into 5387 6 times, leaving a remainder of 347.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we subtract 5040 from 5387, we get 347.
Fetch the next digit (5) from the dividend, attach it to 347 and continue: 3475 / 840

On to step 6:
840 can be fit into 3475 4 times, resulting in a remainder of 115.
Write down 4 as next digit of the result. 
Result so far: 1164.0
Deduct 3360 from 3475 and we're left with 115.
Grab the next digit (7) from the dividend, add it to 115, then carry on: 1157 / 840

Let's proceed to step 7:
The number 840 fits into 1157 1 times, leaving a remainder of 317.
Put 1 as the next digit of the answer. 
Result so far: 11641.0
If we subtract 840 from 1157, we get 317.
Take the next digit (5) from the dividend and append it to 317, then repeat: 3175 / 840

Moving on to step 8:
When dividing 3175 by 840, we get 3 with a remainder of 655.
Write down 3 as next digit of the result. 
Result so far: 116413.0
If we subtract 2520 from 3175, we get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Advancing to step 9:
If we divide 6550 by 840, we get 7 and a remainder of 670.
Put 7 as the next digit of the answer. 
Result so far: 116413.7
If we take 5880 away from 6550, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Advancing to step 10:
When dividing 6700 by 840, we get 7 with a remainder of 820.
Write down 7 as next digit of the result. 
Result so far: 116413.77
The remainder is 820 after subtracting 5880 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

The quotient of the division is 116413.77, and the remainder is 0.82.
