We look at the division of 53719840 by 438 
We want to figure out the number of times 53719840 can be divided by 438.

Advancing to step 1:
When dividing 5 by 438, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 438

Let's proceed to step 2:
When dividing 53 by 438, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 438

Let's proceed to step 3:
537 divided by 438 is 1 with a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 438 from 537 and we're left with 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 438

Moving on to step 4:
438 can be fit into 991 2 times, resulting in a remainder of 115.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 876 away from 991, we end up with 115.
Bring next digit (9) of the dividend behind the 115 and repeat the process: 1159 / 438

Going ahead to step 5:
If we divide 1159 by 438, we get 2 and a remainder of 283.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
If we take 876 away from 1159, we end up with 283.
Include the next digit (8) from the dividend after 283, then repeat: 2838 / 438

Advancing to step 6:
The number 438 fits into 2838 6 times, leaving a remainder of 210.
The number 6 becomes the next digit in our result. 
Result so far: 1226.0
Deduct 2628 from 2838 and we're left with 210.
Bring next digit (4) of the dividend behind the 210 and repeat the process: 2104 / 438

Advancing to step 7:
The number 438 fits into 2104 4 times, leaving a remainder of 352.
Write down 4 as next digit of the result. 
Result so far: 12264.0
Subtracting 1752 from 2104 leaves us with 352.
Fetch the next digit (0) from the dividend, attach it to 352 and continue: 3520 / 438

On to step 8:
438 goes into 3520 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 122648.0
Deduct 3504 from 3520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
When dividing 160 by 438, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 122648.0
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
1600 divided by 438 is 3 with a remainder of 286.
Put 3 as the next digit of the answer. 
Result so far: 122648.03
Subtracting 1314 from 1600 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 11:
438 goes into 2860 6 times with a remainder of 232.
Use 6 as the next digit of our solution. 
Result so far: 122648.036
The remainder is 232 after subtracting 2628 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 12:
438 can be fit into 2320 5 times, resulting in a remainder of 130.
The next digit of our result is 5. 
Result so far: 122648.0365
Deduct 2190 from 2320 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 13:
438 goes into 1300 2 times with a remainder of 424.
The number 2 becomes the next digit in our result. 
Result so far: 122648.03652
Deduct 876 from 1300 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 14:
The number 438 fits into 4240 9 times, leaving a remainder of 298.
Put 9 as the next digit of the answer. 
Result so far: 122648.036529
If we subtract 3942 from 4240, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 15:
438 goes into 2980 6 times with a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 122648.0365296
Subtracting 2628 from 2980 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 16:
If we divide 3520 by 438, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 122648.03652968
Deduct 3504 from 3520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 122648.03652968 with a balance of 1.6e-08.
