Let's divide 39770958 by 421
Let's see how many times 421 fits into 39770958.

Going ahead to step 1:
The number 421 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 421

Going ahead to step 2:
39 divided by 421 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 421

Let's proceed to step 3:
When dividing 397 by 421, we get 0 with a remainder of 397.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 397 and we're left with 397.
Append the next digit (7) from the dividend to 397 and continue with: 3977 / 421

Step 4:
3977 divided by 421 is 9 with a remainder of 188.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 188 after subtracting 3789 from 3977.
Include the next digit (0) from the dividend after 188, then repeat: 1880 / 421

Step 5:
If we divide 1880 by 421, we get 4 and a remainder of 196.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Subtracting 1684 from 1880 leaves us with 196.
Append the next digit (9) from the dividend to 196 and continue with: 1969 / 421

Going ahead to step 6:
1969 divided by 421 is 4 with a remainder of 285.
Use 4 as the next digit of our solution. 
Result so far: 944.0
Subtract 1684 from 1969 to get 285.
Take the next digit (5) from the dividend and append it to 285, then repeat: 2855 / 421

Step 7:
The number 421 fits into 2855 6 times, leaving a remainder of 329.
Put 6 as the next digit of the answer. 
Result so far: 9446.0
Deduct 2526 from 2855 and we're left with 329.
Bring next digit (8) of the dividend behind the 329 and repeat the process: 3298 / 421

Advancing to step 8:
3298 divided by 421 is 7 with a remainder of 351.
Write down 7 as next digit of the result. 
Result so far: 94467.0
Deduct 2947 from 3298 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 9:
When dividing 3510 by 421, we get 8 with a remainder of 142.
The next digit of our result is 8. 
Result so far: 94467.8
Subtract 3368 from 3510 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 10:
When dividing 1420 by 421, we get 3 with a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 94467.83
Deduct 1263 from 1420 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 11:
When dividing 1570 by 421, we get 3 with a remainder of 307.
Use 3 as the next digit of our solution. 
Result so far: 94467.833
Subtracting 1263 from 1570 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Our division results in 94467.833 with a remaining 0.0307.
