76053770 ÷ 421 
We want to divide 76053770 by 421.

Let's proceed to step 1:
If we divide 7 by 421, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 421

Step 2:
The number 421 fits into 76 0 times, leaving a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 421

Step 3:
The number 421 fits into 760 1 times, leaving a remainder of 339.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 421 from 760 and we're left with 339.
Append the next digit (5) from the dividend to 339 and continue with: 3395 / 421

Let's proceed to step 4:
If we divide 3395 by 421, we get 8 and a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 27 after subtracting 3368 from 3395.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 421

Advancing to step 5:
If we divide 273 by 421, we get 0 and a remainder of 273.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
Deduct 0 from 273 and we're left with 273.
Include the next digit (7) from the dividend after 273, then repeat: 2737 / 421

Let's proceed to step 6:
When dividing 2737 by 421, we get 6 with a remainder of 211.
Record the quotient 6 as the next digit in the result. 
Result so far: 1806.0
Deduct 2526 from 2737 and we're left with 211.
Bring next digit (7) of the dividend behind the 211 and repeat the process: 2117 / 421

Moving on to step 7:
2117 divided by 421 is 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 18065.0
The remainder is 12 after subtracting 2105 from 2117.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 421

Let's proceed to step 8:
120 divided by 421 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 180650.0
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 9:
421 goes into 1200 2 times with a remainder of 358.
The next digit of our result is 2. 
Result so far: 180650.2
If we take 842 away from 1200, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 10:
3580 divided by 421 is 8 with a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 180650.28
Deduct 3368 from 3580 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 11:
When dividing 2120 by 421, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 180650.285
If we subtract 2105 from 2120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
150 divided by 421 is 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 180650.285
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 13:
1500 divided by 421 is 3 with a remainder of 237.
Write down 3 as next digit of the result. 
Result so far: 180650.28503
If we take 1263 away from 1500, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 14:
2370 divided by 421 is 5 with a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 180650.285035
If we take 2105 away from 2370, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 15:
421 goes into 2650 6 times with a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 180650.2850356
If we subtract 2526 from 2650, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 16:
421 can be fit into 1240 2 times, resulting in a remainder of 398.
The number 2 becomes the next digit in our result. 
Result so far: 180650.28503562
If we take 842 away from 1240, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

The final outcome is 180650.28503562, with a leftover of 3.98e-07.
