We look at the division of 91530577 by 840 
We want to figure out the number of times 91530577 can be divided by 840.

Moving on to step 1:
9 divided by 840 is 0 with 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 (1) from the dividend after 9, then repeat: 91 / 840

On to step 2:
840 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Grab the next digit (5) from the dividend, add it to 91, then carry on: 915 / 840

Step 3:
The number 840 fits into 915 1 times, leaving a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 840 from 915 to get 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 840

Moving on to step 4:
When dividing 753 by 840, we get 0 with a remainder of 753.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 753, we end up with 753.
Bring next digit (0) of the dividend behind the 753 and repeat the process: 7530 / 840

Let's proceed to step 5:
7530 divided by 840 is 8 with a remainder of 810.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
The remainder is 810 after subtracting 6720 from 7530.
Include the next digit (5) from the dividend after 810, then repeat: 8105 / 840

Moving on to step 6:
840 can be fit into 8105 9 times, resulting in a remainder of 545.
The next digit of our result is 9. 
Result so far: 1089.0
Deduct 7560 from 8105 and we're left with 545.
Append the next digit (7) from the dividend to 545 and continue with: 5457 / 840

Let's proceed to step 7:
5457 divided by 840 is 6 with a remainder of 417.
The next digit of our result is 6. 
Result so far: 10896.0
If we take 5040 away from 5457, we end up with 417.
Bring next digit (7) of the dividend behind the 417 and repeat the process: 4177 / 840

On to step 8:
4177 divided by 840 is 4 with a remainder of 817.
Put 4 as the next digit of the answer. 
Result so far: 108964.0
Subtracting 3360 from 4177 leaves us with 817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8170, and continue the process.

Advancing to step 9:
When dividing 8170 by 840, we get 9 with a remainder of 610.
Use 9 as the next digit of our solution. 
Result so far: 108964.9
If we take 7560 away from 8170, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 10:
The number 840 fits into 6100 7 times, leaving a remainder of 220.
Use 7 as the next digit of our solution. 
Result so far: 108964.97
Subtracting 5880 from 6100 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 11:
The number 840 fits into 2200 2 times, leaving a remainder of 520.
Put 2 as the next digit of the answer. 
Result so far: 108964.972
Subtract 1680 from 2200 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 12:
The number 840 fits into 5200 6 times, leaving a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 108964.9726
Subtracting 5040 from 5200 leaves us 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.

Let's proceed to step 13:
If we divide 1600 by 840, we get 1 and a remainder of 760.
Write down 1 as next digit of the result. 
Result so far: 108964.97261
Deduct 840 from 1600 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 14:
If we divide 7600 by 840, we get 9 and a remainder of 40.
The next digit of our result is 9. 
Result so far: 108964.972619
Subtracting 7560 from 7600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
840 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 108964.972619
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 16:
If we divide 4000 by 840, we get 4 and a remainder of 640.
The number 4 becomes the next digit in our result. 
Result so far: 108964.97261904
If we take 3360 away from 4000, we end up 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.

After the division, we end up with 108964.97261904 and a remainder of 6.4e-07.
