18437542 divided by 840 
We want to divide 18437542 by 840.

Advancing to step 1:
If we divide 1 by 840, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 840

Let's proceed to step 2:
840 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 840

On to step 3:
840 can be fit into 184 0 times, resulting in a remainder of 184.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 184, we get 184.
Bring next digit (3) of the dividend behind the 184 and repeat the process: 1843 / 840

Let's proceed to step 4:
1843 divided by 840 is 2 with a remainder of 163.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1680 away from 1843, we end up with 163.
Grab the next digit (7) from the dividend, add it to 163, then carry on: 1637 / 840

On to step 5:
When dividing 1637 by 840, we get 1 with a remainder of 797.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 840 from 1637 leaves us with 797.
Include the next digit (5) from the dividend after 797, then repeat: 7975 / 840

Going ahead to step 6:
If we divide 7975 by 840, we get 9 and a remainder of 415.
Write down 9 as next digit of the result. 
Result so far: 219.0
Subtracting 7560 from 7975 leaves us with 415.
Bring next digit (4) of the dividend behind the 415 and repeat the process: 4154 / 840

Let's proceed to step 7:
When dividing 4154 by 840, we get 4 with a remainder of 794.
Record the quotient 4 as the next digit in the result. 
Result so far: 2194.0
Subtracting 3360 from 4154 leaves us with 794.
Take the next digit (2) from the dividend and append it to 794, then repeat: 7942 / 840

Advancing to step 8:
The number 840 fits into 7942 9 times, leaving a remainder of 382.
The next digit of our result is 9. 
Result so far: 21949.0
If we take 7560 away from 7942, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 9:
840 goes into 3820 4 times with a remainder of 460.
Put 4 as the next digit of the answer. 
Result so far: 21949.4
The remainder is 460 after subtracting 3360 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 10:
When dividing 4600 by 840, we get 5 with a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 21949.45
Deduct 4200 from 4600 and we're left 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.

Going ahead to step 11:
The number 840 fits into 4000 4 times, leaving a remainder of 640.
The next digit of our result is 4. 
Result so far: 21949.454
If we subtract 3360 from 4000, we get 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:
840 can be fit into 6400 7 times, resulting in a remainder of 520.
Write down 7 as next digit of the result. 
Result so far: 21949.4547
If we take 5880 away from 6400, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 13:
If we divide 5200 by 840, we get 6 and a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 21949.45476
The remainder is 160 after subtracting 5040 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
If we divide 1600 by 840, we get 1 and a remainder of 760.
Record the quotient 1 as the next digit in the result. 
Result so far: 21949.454761
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.

Let's proceed to step 15:
When dividing 7600 by 840, we get 9 with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 21949.4547619
The remainder is 40 after subtracting 7560 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
400 divided by 840 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 21949.4547619
If we take 0 away from 400, we end up 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.

The final outcome is 21949.4547619, with a leftover of 4e-07.
