45874344 divided by 421 
We want to divide 45874344 by 421.

Let's proceed to step 1:
When dividing 4 by 421, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 421

Let's proceed to step 2:
421 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 421

Advancing to step 3:
The number 421 fits into 458 1 times, leaving a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 37 after subtracting 421 from 458.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 421

Let's proceed to step 4:
When dividing 377 by 421, we get 0 with a remainder of 377.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 377 and we're left with 377.
Fetch the next digit (4) from the dividend, attach it to 377 and continue: 3774 / 421

On to step 5:
421 can be fit into 3774 8 times, resulting in a remainder of 406.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 406 after subtracting 3368 from 3774.
Grab the next digit (3) from the dividend, add it to 406, then carry on: 4063 / 421

Going ahead to step 6:
421 goes into 4063 9 times with a remainder of 274.
Record the quotient 9 as the next digit in the result. 
Result so far: 1089.0
If we take 3789 away from 4063, we end up with 274.
Grab the next digit (4) from the dividend, add it to 274, then carry on: 2744 / 421

Let's proceed to step 7:
When dividing 2744 by 421, we get 6 with a remainder of 218.
Write down 6 as next digit of the result. 
Result so far: 10896.0
Deduct 2526 from 2744 and we're left with 218.
Grab the next digit (4) from the dividend, add it to 218, then carry on: 2184 / 421

Advancing to step 8:
When dividing 2184 by 421, we get 5 with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 108965.0
If we subtract 2105 from 2184, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
When dividing 790 by 421, we get 1 with a remainder of 369.
The next digit of our result is 1. 
Result so far: 108965.1
If we subtract 421 from 790, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Advancing to step 10:
When dividing 3690 by 421, we get 8 with a remainder of 322.
The next digit of our result is 8. 
Result so far: 108965.18
Deduct 3368 from 3690 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 11:
If we divide 3220 by 421, we get 7 and a remainder of 273.
Record the quotient 7 as the next digit in the result. 
Result so far: 108965.187
If we take 2947 away from 3220, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 12:
421 goes into 2730 6 times with a remainder of 204.
The next digit of our result is 6. 
Result so far: 108965.1876
Deduct 2526 from 2730 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 13:
When dividing 2040 by 421, we get 4 with a remainder of 356.
Use 4 as the next digit of our solution. 
Result so far: 108965.18764
Subtract 1684 from 2040 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 14:
If we divide 3560 by 421, we get 8 and a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 108965.187648
Deduct 3368 from 3560 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 15:
If we divide 1920 by 421, we get 4 and a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 108965.1876484
Subtracting 1684 from 1920 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 16:
2360 divided by 421 is 5 with a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 108965.18764845
Subtract 2105 from 2360 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 108965.18764845 with a remainder of 2.55e-07.
