We look at the division of 42954572 by 307 
We want to divide 42954572 by 307.

Advancing to step 1:
307 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 307

On to step 2:
42 divided by 307 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 307

Advancing to step 3:
The number 307 fits into 429 1 times, leaving a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 122 after subtracting 307 from 429.
Grab the next digit (5) from the dividend, add it to 122, then carry on: 1225 / 307

Advancing to step 4:
1225 divided by 307 is 3 with a remainder of 304.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 921 from 1225 and we're left with 304.
Bring next digit (4) of the dividend behind the 304 and repeat the process: 3044 / 307

Moving on to step 5:
3044 divided by 307 is 9 with a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtracting 2763 from 3044 leaves us with 281.
Grab the next digit (5) from the dividend, add it to 281, then carry on: 2815 / 307

Step 6:
When dividing 2815 by 307, we get 9 with a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 1399.0
The remainder is 52 after subtracting 2763 from 2815.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 307

On to step 7:
307 can be fit into 527 1 times, resulting in a remainder of 220.
The next digit of our result is 1. 
Result so far: 13991.0
Deduct 307 from 527 and we're left with 220.
Fetch the next digit (2) from the dividend, attach it to 220 and continue: 2202 / 307

Let's proceed to step 8:
307 can be fit into 2202 7 times, resulting in a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 139917.0
If we subtract 2149 from 2202, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
If we divide 530 by 307, we get 1 and a remainder of 223.
Use 1 as the next digit of our solution. 
Result so far: 139917.1
If we take 307 away from 530, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 10:
When dividing 2230 by 307, we get 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 139917.17
If we take 2149 away from 2230, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 11:
When dividing 810 by 307, we get 2 with a remainder of 196.
Record the quotient 2 as the next digit in the result. 
Result so far: 139917.172
If we subtract 614 from 810, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 12:
307 can be fit into 1960 6 times, resulting in a remainder of 118.
The next digit of our result is 6. 
Result so far: 139917.1726
Deduct 1842 from 1960 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 13:
307 can be fit into 1180 3 times, resulting in a remainder of 259.
The number 3 becomes the next digit in our result. 
Result so far: 139917.17263
Subtracting 921 from 1180 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 14:
307 can be fit into 2590 8 times, resulting in a remainder of 134.
Write down 8 as next digit of the result. 
Result so far: 139917.172638
If we subtract 2456 from 2590, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 15:
1340 divided by 307 is 4 with a remainder of 112.
The next digit of our result is 4. 
Result so far: 139917.1726384
If we take 1228 away from 1340, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 16:
1120 divided by 307 is 3 with a remainder of 199.
The next digit of our result is 3. 
Result so far: 139917.17263843
Subtracting 921 from 1120 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

The final result is 139917.17263843 with a remainder of 1.99e-07.
