37937120 divided by 421 
Our goal is to divide 37937120 by 421.

Moving on to step 1:
If we divide 3 by 421, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 421

Going ahead to step 2:
37 divided by 421 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 421

On to step 3:
421 goes into 379 0 times with a remainder of 379.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 379, we end up with 379.
Append the next digit (3) from the dividend to 379 and continue with: 3793 / 421

On to step 4:
421 can be fit into 3793 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 3789 from 3793 leaves us with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 421

Step 5:
If we divide 47 by 421, we get 0 and a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 47 to get 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 421

On to step 6:
The number 421 fits into 471 1 times, leaving a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 901.0
If we take 421 away from 471, we end up with 50.
Append the next digit (2) from the dividend to 50 and continue with: 502 / 421

Let's proceed to step 7:
The number 421 fits into 502 1 times, leaving a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 9011.0
Deduct 421 from 502 and we're left with 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 421

On to step 8:
The number 421 fits into 810 1 times, leaving a remainder of 389.
Record the quotient 1 as the next digit in the result. 
Result so far: 90111.0
The remainder is 389 after subtracting 421 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 9:
If we divide 3890 by 421, we get 9 and a remainder of 101.
Record the quotient 9 as the next digit in the result. 
Result so far: 90111.9
The remainder is 101 after subtracting 3789 from 3890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 10:
421 can be fit into 1010 2 times, resulting in a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 90111.92
The remainder is 168 after subtracting 842 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 11:
When dividing 1680 by 421, we get 3 with a remainder of 417.
Use 3 as the next digit of our solution. 
Result so far: 90111.923
Subtracting 1263 from 1680 leaves us with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Moving on to step 12:
When dividing 4170 by 421, we get 9 with a remainder of 381.
Put 9 as the next digit of the answer. 
Result so far: 90111.9239
If we take 3789 away from 4170, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Advancing to step 13:
421 can be fit into 3810 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 90111.92399
Deduct 3789 from 3810 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 90111.92399, and the remainder is 2.1e-05.
