10610837 ÷ 840 
Let's see how many times 840 fits into 10610837.

On to step 1:
840 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 840

Step 2:
When dividing 10 by 840, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 840

Advancing to step 3:
If we divide 106 by 840, we get 0 and a remainder of 106.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 106 leaves us with 106.
Append the next digit (1) from the dividend to 106 and continue with: 1061 / 840

On to step 4:
840 can be fit into 1061 1 times, resulting in a remainder of 221.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 840 from 1061 to get 221.
Bring next digit (0) of the dividend behind the 221 and repeat the process: 2210 / 840

Moving on to step 5:
2210 divided by 840 is 2 with a remainder of 530.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1680 from 2210 and we're left with 530.
Append the next digit (8) from the dividend to 530 and continue with: 5308 / 840

Let's proceed to step 6:
If we divide 5308 by 840, we get 6 and a remainder of 268.
The next digit of our result is 6. 
Result so far: 126.0
Subtract 5040 from 5308 to get 268.
Take the next digit (3) from the dividend and append it to 268, then repeat: 2683 / 840

Step 7:
The number 840 fits into 2683 3 times, leaving a remainder of 163.
The number 3 becomes the next digit in our result. 
Result so far: 1263.0
If we subtract 2520 from 2683, we get 163.
Append the next digit (7) from the dividend to 163 and continue with: 1637 / 840

Let's proceed to step 8:
1637 divided by 840 is 1 with a remainder of 797.
Use 1 as the next digit of our solution. 
Result so far: 12631.0
If we take 840 away from 1637, we end up with 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Step 9:
When dividing 7970 by 840, we get 9 with a remainder of 410.
The next digit of our result is 9. 
Result so far: 12631.9
Subtract 7560 from 7970 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 10:
When dividing 4100 by 840, we get 4 with a remainder of 740.
Write down 4 as next digit of the result. 
Result so far: 12631.94
If we subtract 3360 from 4100, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 11:
The number 840 fits into 7400 8 times, leaving a remainder of 680.
Record the quotient 8 as the next digit in the result. 
Result so far: 12631.948
Subtracting 6720 from 7400 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 12:
If we divide 6800 by 840, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 12631.9488
If we subtract 6720 from 6800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 12631.9488 with a remainder of 0.0008.
