61974621 ÷ 57 
We want to figure out the number of times 61974621 can be divided by 57.

Step 1:
When dividing 6 by 57, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 57

Let's proceed to step 2:
57 goes into 61 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 57 from 61 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 57

On to step 3:
When dividing 49 by 57, we get 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 49 and we're left with 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 57

Moving on to step 4:
57 goes into 497 8 times with a remainder of 41.
The next digit of our result is 8. 
Result so far: 108.0
Subtract 456 from 497 to get 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 57

Let's proceed to step 5:
57 can be fit into 414 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 1087.0
Subtract 399 from 414 to get 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 57

Advancing to step 6:
57 can be fit into 156 2 times, resulting in a remainder of 42.
The next digit of our result is 2. 
Result so far: 10872.0
Deduct 114 from 156 and we're left with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 57

Going ahead to step 7:
57 goes into 422 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 108727.0
If we take 399 away from 422, we end up with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 57

On to step 8:
If we divide 231 by 57, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 1087274.0
Deduct 228 from 231 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
30 divided by 57 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1087274.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
When dividing 300 by 57, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1087274.05
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
If we divide 150 by 57, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 1087274.052
Subtracting 114 from 150 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 57, we get 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 1087274.0526
Deduct 342 from 360 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
57 goes into 180 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 1087274.05263
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
90 divided by 57 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1087274.052631
Subtract 57 from 90 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 15:
When dividing 330 by 57, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 1087274.0526315
If we take 285 away from 330, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 16:
57 can be fit into 450 7 times, resulting in a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 1087274.05263157
The remainder is 51 after subtracting 399 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 1087274.05263157 and a remainder of 5.1e-08.
