We're dividing 83722678 by 840 
Let's see how many times 840 fits into 83722678.

Let's proceed to step 1:
The number 840 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 840

Moving on to step 2:
840 can be fit into 83 0 times, resulting in a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 840

Let's proceed to step 3:
When dividing 837 by 840, we get 0 with a remainder of 837.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 837 and we're left with 837.
Append the next digit (2) from the dividend to 837 and continue with: 8372 / 840

Going ahead to step 4:
When dividing 8372 by 840, we get 9 with a remainder of 812.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7560 from 8372 to get 812.
Fetch the next digit (2) from the dividend, attach it to 812 and continue: 8122 / 840

Let's proceed to step 5:
840 can be fit into 8122 9 times, resulting in a remainder of 562.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 7560 from 8122 to get 562.
Append the next digit (6) from the dividend to 562 and continue with: 5626 / 840

Going ahead to step 6:
If we divide 5626 by 840, we get 6 and a remainder of 586.
Record the quotient 6 as the next digit in the result. 
Result so far: 996.0
If we subtract 5040 from 5626, we get 586.
Take the next digit (7) from the dividend and append it to 586, then repeat: 5867 / 840

Let's proceed to step 7:
If we divide 5867 by 840, we get 6 and a remainder of 827.
The next digit of our result is 6. 
Result so far: 9966.0
Subtracting 5040 from 5867 leaves us with 827.
Fetch the next digit (8) from the dividend, attach it to 827 and continue: 8278 / 840

Step 8:
840 can be fit into 8278 9 times, resulting in a remainder of 718.
The next digit of our result is 9. 
Result so far: 99669.0
If we take 7560 away from 8278, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Step 9:
840 goes into 7180 8 times with a remainder of 460.
Write down 8 as next digit of the result. 
Result so far: 99669.8
Deduct 6720 from 7180 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 10:
The number 840 fits into 4600 5 times, leaving a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 99669.85
If we subtract 4200 from 4600, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 11:
When dividing 4000 by 840, we get 4 with a remainder of 640.
The number 4 becomes the next digit in our result. 
Result so far: 99669.854
Subtracting 3360 from 4000 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 12:
If we divide 6400 by 840, we get 7 and a remainder of 520.
Record the quotient 7 as the next digit in the result. 
Result so far: 99669.8547
Subtract 5880 from 6400 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 13:
The number 840 fits into 5200 6 times, leaving a remainder of 160.
The next digit of our result is 6. 
Result so far: 99669.85476
If we take 5040 away from 5200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
The number 840 fits into 1600 1 times, leaving a remainder of 760.
Use 1 as the next digit of our solution. 
Result so far: 99669.854761
The remainder is 760 after subtracting 840 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 15:
The number 840 fits into 7600 9 times, leaving a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 99669.8547619
If we subtract 7560 from 7600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
840 goes into 400 0 times with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 99669.8547619
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 99669.8547619, with a leftover of 4e-07.
