We divide 73189841 by 421
We want to divide 73189841 by 421.

Moving on to step 1:
7 divided by 421 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 421

Moving on to step 2:
421 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 421

Step 3:
The number 421 fits into 731 1 times, leaving a remainder of 310.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 421 from 731, we get 310.
Bring next digit (8) of the dividend behind the 310 and repeat the process: 3108 / 421

Advancing to step 4:
If we divide 3108 by 421, we get 7 and a remainder of 161.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 2947 away from 3108, we end up with 161.
Fetch the next digit (9) from the dividend, attach it to 161 and continue: 1619 / 421

Advancing to step 5:
If we divide 1619 by 421, we get 3 and a remainder of 356.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
If we take 1263 away from 1619, we end up with 356.
Take the next digit (8) from the dividend and append it to 356, then repeat: 3568 / 421

On to step 6:
421 can be fit into 3568 8 times, resulting in a remainder of 200.
The next digit of our result is 8. 
Result so far: 1738.0
Subtract 3368 from 3568 to get 200.
Fetch the next digit (4) from the dividend, attach it to 200 and continue: 2004 / 421

Moving on to step 7:
The number 421 fits into 2004 4 times, leaving a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 17384.0
If we take 1684 away from 2004, we end up with 320.
Include the next digit (1) from the dividend after 320, then repeat: 3201 / 421

Step 8:
421 goes into 3201 7 times with a remainder of 254.
Use 7 as the next digit of our solution. 
Result so far: 173847.0
The remainder is 254 after subtracting 2947 from 3201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 9:
2540 divided by 421 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 173847.6
If we take 2526 away from 2540, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
140 divided by 421 is 0 with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 173847.6
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
If we divide 1400 by 421, we get 3 and a remainder of 137.
Record the quotient 3 as the next digit in the result. 
Result so far: 173847.603
If we take 1263 away from 1400, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 12:
The number 421 fits into 1370 3 times, leaving a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 173847.6033
Subtract 1263 from 1370 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Our division results in 173847.6033 with a remaining 0.00107.
