37564993 ÷ 421 
We want to divide 37564993 by 421.

On to step 1:
421 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 421

Let's proceed to step 2:
37 divided by 421 is 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 421

Step 3:
421 can be fit into 375 0 times, resulting in a remainder of 375.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 375 to get 375.
Take the next digit (6) from the dividend and append it to 375, then repeat: 3756 / 421

Moving on to step 4:
The number 421 fits into 3756 8 times, leaving a remainder of 388.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 388 after subtracting 3368 from 3756.
Append the next digit (4) from the dividend to 388 and continue with: 3884 / 421

Let's proceed to step 5:
When dividing 3884 by 421, we get 9 with a remainder of 95.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Deduct 3789 from 3884 and we're left with 95.
Bring next digit (9) of the dividend behind the 95 and repeat the process: 959 / 421

Moving on to step 6:
959 divided by 421 is 2 with a remainder of 117.
Write down 2 as next digit of the result. 
Result so far: 892.0
Subtracting 842 from 959 leaves us with 117.
Include the next digit (9) from the dividend after 117, then repeat: 1179 / 421

Moving on to step 7:
1179 divided by 421 is 2 with a remainder of 337.
The number 2 becomes the next digit in our result. 
Result so far: 8922.0
Subtract 842 from 1179 to get 337.
Include the next digit (3) from the dividend after 337, then repeat: 3373 / 421

Step 8:
The number 421 fits into 3373 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 89228.0
Deduct 3368 from 3373 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
421 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 89228.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
421 can be fit into 500 1 times, resulting in a remainder of 79.
The next digit of our result is 1. 
Result so far: 89228.01
Subtracting 421 from 500 leaves us with 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 11:
The number 421 fits into 790 1 times, leaving a remainder of 369.
Put 1 as the next digit of the answer. 
Result so far: 89228.011
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.

The quotient of the division is 89228.011, and the remainder is 0.0369.
