We're dividing 57377934 by 420 
Let's see how many times 420 fits into 57377934.

Advancing to step 1:
420 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 420

Let's proceed to step 2:
If we divide 57 by 420, we get 0 and a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 420

Going ahead to step 3:
If we divide 573 by 420, we get 1 and a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 420 from 573 to get 153.
Bring next digit (7) of the dividend behind the 153 and repeat the process: 1537 / 420

On to step 4:
420 goes into 1537 3 times with a remainder of 277.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1260 from 1537, we get 277.
Append the next digit (7) from the dividend to 277 and continue with: 2777 / 420

Advancing to step 5:
2777 divided by 420 is 6 with a remainder of 257.
Write down 6 as next digit of the result. 
Result so far: 136.0
The remainder is 257 after subtracting 2520 from 2777.
Append the next digit (9) from the dividend to 257 and continue with: 2579 / 420

Advancing to step 6:
420 goes into 2579 6 times with a remainder of 59.
Put 6 as the next digit of the answer. 
Result so far: 1366.0
Subtract 2520 from 2579 to get 59.
Include the next digit (3) from the dividend after 59, then repeat: 593 / 420

Let's proceed to step 7:
If we divide 593 by 420, we get 1 and a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 13661.0
Subtracting 420 from 593 leaves us with 173.
Bring next digit (4) of the dividend behind the 173 and repeat the process: 1734 / 420

On to step 8:
420 goes into 1734 4 times with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 136614.0
If we take 1680 away from 1734, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
540 divided by 420 is 1 with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 136614.1
If we subtract 420 from 540, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
When dividing 1200 by 420, we get 2 with a remainder of 360.
The next digit of our result is 2. 
Result so far: 136614.12
If we take 840 away from 1200, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 11:
3600 divided by 420 is 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 136614.128
Subtracting 3360 from 3600 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
If we divide 2400 by 420, we get 5 and a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 136614.1285
If we subtract 2100 from 2400, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
When dividing 3000 by 420, we get 7 with a remainder of 60.
The next digit of our result is 7. 
Result so far: 136614.12857
Subtracting 2940 from 3000 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
600 divided by 420 is 1 with a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 136614.128571
If we take 420 away from 600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 15:
420 can be fit into 1800 4 times, resulting in a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 136614.1285714
If we subtract 1680 from 1800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
420 can be fit into 1200 2 times, resulting in a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 136614.12857142
If we subtract 840 from 1200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 136614.12857142, and the remainder is 3.6e-07.
