We look at the division of 30753671 by 840 
We want to figure out the number of times 30753671 can be divided by 840.

Moving on to step 1:
When dividing 3 by 840, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 840

On to step 2:
840 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 840

Moving on to step 3:
When dividing 307 by 840, we get 0 with a remainder of 307.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 307 to get 307.
Include the next digit (5) from the dividend after 307, then repeat: 3075 / 840

On to step 4:
840 goes into 3075 3 times with a remainder of 555.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 555 after subtracting 2520 from 3075.
Take the next digit (3) from the dividend and append it to 555, then repeat: 5553 / 840

Let's proceed to step 5:
When dividing 5553 by 840, we get 6 with a remainder of 513.
The next digit of our result is 6. 
Result so far: 36.0
If we subtract 5040 from 5553, we get 513.
Append the next digit (6) from the dividend to 513 and continue with: 5136 / 840

Going ahead to step 6:
5136 divided by 840 is 6 with a remainder of 96.
The next digit of our result is 6. 
Result so far: 366.0
The remainder is 96 after subtracting 5040 from 5136.
Take the next digit (7) from the dividend and append it to 96, then repeat: 967 / 840

Advancing to step 7:
If we divide 967 by 840, we get 1 and a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 3661.0
If we subtract 840 from 967, we get 127.
Append the next digit (1) from the dividend to 127 and continue with: 1271 / 840

Step 8:
If we divide 1271 by 840, we get 1 and a remainder of 431.
Record the quotient 1 as the next digit in the result. 
Result so far: 36611.0
Deduct 840 from 1271 and we're left with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Going ahead to step 9:
840 can be fit into 4310 5 times, resulting in a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 36611.5
Deduct 4200 from 4310 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
The number 840 fits into 1100 1 times, leaving a remainder of 260.
Record the quotient 1 as the next digit in the result. 
Result so far: 36611.51
If we subtract 840 from 1100, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 11:
When dividing 2600 by 840, we get 3 with a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 36611.513
Subtracting 2520 from 2600 leaves us with 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 12:
If we divide 800 by 840, we get 0 and a remainder of 800.
The next digit of our result is 0. 
Result so far: 36611.513
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.

Step 13:
When dividing 8000 by 840, we get 9 with a remainder of 440.
Use 9 as the next digit of our solution. 
Result so far: 36611.51309
Deduct 7560 from 8000 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 14:
When dividing 4400 by 840, we get 5 with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 36611.513095
Deduct 4200 from 4400 and we're left 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 15:
The number 840 fits into 2000 2 times, leaving a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 36611.5130952
Deduct 1680 from 2000 and we're left 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.

Let's proceed to step 16:
If we divide 3200 by 840, we get 3 and a remainder of 680.
Use 3 as the next digit of our solution. 
Result so far: 36611.51309523
Deduct 2520 from 3200 and we're left 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.

The final result is 36611.51309523 with a remainder of 6.8e-07.
