Let's divide 98699319 by 840
We want to divide 98699319 by 840.

Going ahead to step 1:
If we divide 9 by 840, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 840

Step 2:
The number 840 fits into 98 0 times, leaving a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Take the next digit (6) from the dividend and append it to 98, then repeat: 986 / 840

On to step 3:
986 divided by 840 is 1 with a remainder of 146.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 146 after subtracting 840 from 986.
Grab the next digit (9) from the dividend, add it to 146, then carry on: 1469 / 840

Step 4:
1469 divided by 840 is 1 with a remainder of 629.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 840 from 1469, we get 629.
Fetch the next digit (9) from the dividend, attach it to 629 and continue: 6299 / 840

Step 5:
The number 840 fits into 6299 7 times, leaving a remainder of 419.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we subtract 5880 from 6299, we get 419.
Bring next digit (3) of the dividend behind the 419 and repeat the process: 4193 / 840

Going ahead to step 6:
If we divide 4193 by 840, we get 4 and a remainder of 833.
Write down 4 as next digit of the result. 
Result so far: 1174.0
Deduct 3360 from 4193 and we're left with 833.
Fetch the next digit (1) from the dividend, attach it to 833 and continue: 8331 / 840

Moving on to step 7:
When dividing 8331 by 840, we get 9 with a remainder of 771.
The number 9 becomes the next digit in our result. 
Result so far: 11749.0
Deduct 7560 from 8331 and we're left with 771.
Bring next digit (9) of the dividend behind the 771 and repeat the process: 7719 / 840

Advancing to step 8:
840 can be fit into 7719 9 times, resulting in a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 117499.0
Subtract 7560 from 7719 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 9:
When dividing 1590 by 840, we get 1 with a remainder of 750.
The number 1 becomes the next digit in our result. 
Result so far: 117499.1
If we take 840 away from 1590, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 10:
840 goes into 7500 8 times with a remainder of 780.
The next digit of our result is 8. 
Result so far: 117499.18
If we take 6720 away from 7500, we end up 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.

On to step 11:
7800 divided by 840 is 9 with a remainder of 240.
The next digit of our result is 9. 
Result so far: 117499.189
The remainder is 240 after subtracting 7560 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 12:
When dividing 2400 by 840, we get 2 with a remainder of 720.
Put 2 as the next digit of the answer. 
Result so far: 117499.1892
If we take 1680 away from 2400, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 13:
7200 divided by 840 is 8 with a remainder of 480.
The next digit of our result is 8. 
Result so far: 117499.18928
If we take 6720 away from 7200, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 14:
4800 divided by 840 is 5 with a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 117499.189285
If we subtract 4200 from 4800, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 15:
If we divide 6000 by 840, we get 7 and a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 117499.1892857
Subtracting 5880 from 6000 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
1200 divided by 840 is 1 with a remainder of 360.
Put 1 as the next digit of the answer. 
Result so far: 117499.18928571
Subtracting 840 from 1200 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 117499.18928571 and a remainder of 3.6e-07.
