We're dividing 90612608 by 840 
We want to figure out the number of times 90612608 can be divided by 840.

Advancing to step 1:
When dividing 9 by 840, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 840

Step 2:
840 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 840

Step 3:
840 can be fit into 906 1 times, resulting in a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 66 after subtracting 840 from 906.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 840

On to step 4:
840 goes into 661 0 times with a remainder of 661.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 661 leaves us with 661.
Bring next digit (2) of the dividend behind the 661 and repeat the process: 6612 / 840

Step 5:
If we divide 6612 by 840, we get 7 and a remainder of 732.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Deduct 5880 from 6612 and we're left with 732.
Grab the next digit (6) from the dividend, add it to 732, then carry on: 7326 / 840

Moving on to step 6:
840 goes into 7326 8 times with a remainder of 606.
Write down 8 as next digit of the result. 
Result so far: 1078.0
If we subtract 6720 from 7326, we get 606.
Take the next digit (0) from the dividend and append it to 606, then repeat: 6060 / 840

Moving on to step 7:
6060 divided by 840 is 7 with a remainder of 180.
Record the quotient 7 as the next digit in the result. 
Result so far: 10787.0
Subtracting 5880 from 6060 leaves us with 180.
Include the next digit (8) from the dividend after 180, then repeat: 1808 / 840

Let's proceed to step 8:
When dividing 1808 by 840, we get 2 with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 107872.0
Subtracting 1680 from 1808 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 9:
1280 divided by 840 is 1 with a remainder of 440.
The number 1 becomes the next digit in our result. 
Result so far: 107872.1
Deduct 840 from 1280 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 10:
When dividing 4400 by 840, we get 5 with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 107872.15
Subtracting 4200 from 4400 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
840 goes into 2000 2 times with a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 107872.152
Subtracting 1680 from 2000 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
3200 divided by 840 is 3 with a remainder of 680.
Use 3 as the next digit of our solution. 
Result so far: 107872.1523
If we subtract 2520 from 3200, we get 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 13:
6800 divided by 840 is 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 107872.15238
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.

Step 14:
840 goes into 800 0 times with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 107872.15238
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 15:
840 goes into 8000 9 times with a remainder of 440.
Record the quotient 9 as the next digit in the result. 
Result so far: 107872.1523809
The remainder is 440 after subtracting 7560 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 16:
4400 divided by 840 is 5 with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 107872.15238095
If we subtract 4200 from 4400, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 107872.15238095 with a balance of 2e-07.
