61081317 ÷ 840 
We want to figure out the number of times 61081317 can be divided by 840.

On to step 1:
840 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 840

Step 2:
840 can be fit into 61 0 times, resulting in a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 840

Moving on to step 3:
840 goes into 610 0 times with a remainder of 610.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 610 after subtracting 0 from 610.
Take the next digit (8) from the dividend and append it to 610, then repeat: 6108 / 840

Going ahead to step 4:
6108 divided by 840 is 7 with a remainder of 228.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 5880 from 6108 to get 228.
Take the next digit (1) from the dividend and append it to 228, then repeat: 2281 / 840

Moving on to step 5:
The number 840 fits into 2281 2 times, leaving a remainder of 601.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtracting 1680 from 2281 leaves us with 601.
Include the next digit (3) from the dividend after 601, then repeat: 6013 / 840

On to step 6:
If we divide 6013 by 840, we get 7 and a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 727.0
Deduct 5880 from 6013 and we're left with 133.
Bring next digit (1) of the dividend behind the 133 and repeat the process: 1331 / 840

Advancing to step 7:
When dividing 1331 by 840, we get 1 with a remainder of 491.
The next digit of our result is 1. 
Result so far: 7271.0
Subtract 840 from 1331 to get 491.
Append the next digit (7) from the dividend to 491 and continue with: 4917 / 840

Going ahead to step 8:
4917 divided by 840 is 5 with a remainder of 717.
Put 5 as the next digit of the answer. 
Result so far: 72715.0
If we take 4200 away from 4917, we end up with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

On to step 9:
840 goes into 7170 8 times with a remainder of 450.
The next digit of our result is 8. 
Result so far: 72715.8
Subtracting 6720 from 7170 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
If we divide 4500 by 840, we get 5 and a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 72715.85
If we take 4200 away from 4500, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
When dividing 3000 by 840, we get 3 with a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 72715.853
Deduct 2520 from 3000 and we're left 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.

On to step 12:
840 goes into 4800 5 times with a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 72715.8535
If we take 4200 away from 4800, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 13:
The number 840 fits into 6000 7 times, leaving a remainder of 120.
Use 7 as the next digit of our solution. 
Result so far: 72715.85357
Deduct 5880 from 6000 and we're left 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.

Step 14:
The number 840 fits into 1200 1 times, leaving a remainder of 360.
Record the quotient 1 as the next digit in the result. 
Result so far: 72715.853571
If we subtract 840 from 1200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 15:
840 goes into 3600 4 times with a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 72715.8535714
If we subtract 3360 from 3600, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 16:
840 goes into 2400 2 times with a remainder of 720.
The next digit of our result is 2. 
Result so far: 72715.85357142
Subtract 1680 from 2400 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

After the division, we end up with 72715.85357142 and a remainder of 7.2e-07.
